Question: What did Stella talk about to Ted's proposal?
About the article "How I Met Your Mother", section "Season 4".

Candidate passages:
Ted decides that it is time for his relationship with Stella (Sarah Chalke) to take the next step.
Stella is strangely reluctant, however, and she tells Ted a secret: she has not had sex for five years.
Ted shares this with Marshall and Lily, as he does everything.
When Stella comes over on the night that she was meant to have sex with Ted, they accidentally reveal that they know her secret.
Stella is upset that Ted betrayed her trust and breaks up with him.
Meanwhile, Barney tries to find a "Rebound Bro" to whom he can be a wingman to help him get women.
He misses Ted and, unwilling to admit it, puts applications up on his blog.
Receiving few responses except for an enthusiastic proposal from his colleague Randy (Will Forte), Barney resorts to calling up old friends and previous wingmen.
After many unsuccessful attempts (one already has a wingman, one is married and has settled down, etc.)
he decides to be the "Bro" to Randy and give him a chance.
Unfortunately, he discovers that Randy hasn't had sex in thirteen years and Barney is repeatedly unsuccessful at getting him together with a woman, since Randy is uncomfortable with talking to women, and gets nosebleeds whenever he gets an erection.
Barney is unsuccessful until he enlists Robin's help to make Randy comfortable with small-talk with women, telling Robin that he may have a sex tape with her to convince her to come and help Randy.
Barney discovers that Randy was a police officer, albeit one that was fired for incompetence; nevertheless, Barney knows being in the 'force' impresses women, and quickly finds a woman who takes Randy home with her.
Barney seems happy until Robin comments that "Ted doesn't know what he's missing".
Barney tearfully remarks, "You had to mention Ted, didn't you?
"Stella comes to Ted's house and admits that she broke up with him because she was afraid it was getting too serious and she was looking for a reason not to get too close to him.
Ted and Stella's relationship goes even further than expected as Ted meets Stella's daughter and gets to know her.
Later, Stella tells Ted that her sister (who was previously meant to take care of Stella's daughter while Stella and Ted had sex) is still in town and can take care of Stella's daughter.
Stella and Ted rush to a motel, where they finally consummate their relationship.
When Ted jokingly picks up the phone to tell Marshall and Lily about it after the deed is done, Stella pushes him off the bed in an equally lighthearted manner. 
Picking up from the previous episode, Ted turns to see Stella behind him at a crosswalk.
She is quickly joined by her fiance (and father of her daughter), Tony.
Ted says that it's a great surprise to see them, and later at MacLaren's, Barney and Marshall praise his cool.
Later that evening, Tony shows up at Ted's apartment, professing pity for Ted's condition, despite Ted denying any depression on his part.
He explains that his family is rich and wants to make it up to Ted.
First he offers him a professor position at Columbia, which Ted turns down, as it is a last resort in the field of architecture.
Then, Tony brings Ted to a rich friend's house for dinner to offer Ted a job designing a new home.
When the host starts insisting that his "laundry" room be soundproof, lined with stain-proof ceramic tiles, and filled with hanging chains, Ted quickly realizes the man is proposing the design of a "murder room.
"Eventually, Ted rejects Tony's help, claiming he's glad to be rid of Stella, who left him at the altar.
The comment makes Tony reconsider his commitment to Stella, and he breaks off the engagement.
Stella shows up at Ted's apartment distraught, begging him to help her salvage their relationship.
Ted refuses, claiming Stella hurt him and his ability to appreciate love.
Meanwhile, Barney complains about a speeding ticket he receives.
Marshall brags about how he evaded a ticket back in Minnesota by enticing the officer with the offer of bratwurst at a BBQ.
Barney takes this as a challenge, and vows to talk his way out of a ticket, and speeds every time he is driving.
After a few failures, he continues complaining, and Robin tells the story of how she cried her way out of a ticket.
Finally, he encounters an attractive police officer.
In the retelling of the story, Barney claims he promptly seduced the policewoman, but he was actually arrested for numerous moving violations.
Barney calls Ted (who is in the middle of his argument with Stella) from jail in Brazzaville, NJ, desperate to be bailed out (even though he is only in the cell with two teenage vandals).
Stella offers to drive Ted to New Jersey, and the two bail Barney out and drive him back to the city.
Before he exits the car, Ted admits that he is tired of searching for love, and hopes to find what she and Tony have.
Stella tells Ted a story of how she once talked her way out of a speeding ticket: When the officer said "Young lady, I've been waiting for you all day", she replied with "I'm sorry, officer, I got here as fast as I could."
She admits the story was just an old joke and tells Ted the woman meant for him is coming "as fast as she can."
Ted agrees to talk to Tony and the couple get back together.
Future Ted then talks about how Stella established a new, successful dermatological practice on the West Coast, and Tony became a successful screenwriter, with a hit in May 2010 called "The Wedding Bride".
Finally, at the bar, Lily returns, admitting the offensive joke Barney told her four weeks ago was actually funny, but once he starts explaining a scheme involving seducing amnesia patients, she promptly leaves again. 
Future Ted tells his children that the day that he told their mother he loved her was significant because he had not said those words to anyone since he confessed to Robin that he still loved her.
In the aftermath of Ted's confession, he reminds Robin that five years ago their thoughts on the future were too different, and they broke up.
Before they can talk about how Ted's confession could change their platonic relationship and status as room-mates, Robin suddenly has to leave to work on a story in Moscow—she thought she had another twelve hours before she had to leave.
Meanwhile, Barney wakes up at Lily and Marshall's house after taking the "drunk train" and becomes convinced that they have a sex tape hidden somewhere in their house.
While searching for it, he finds a box of long-term bets they have been keeping, one of which involves Lily betting Marshall that Ted and Robin will not end up together.
As Ted tells Marshall and Lily what happened between him and Robin, Barney arrives and calls Marshall and Lily out on their numerous long-term bets.
When Barney learns that one of the bets confirms the existence of a sex tape, he returns to Marshall and Lily's house and eventually finds the tape.
Ted learns of the bet regarding his relationship with Robin and becomes upset with Lily, who forces Ted to consider why he hasn't got back together with Robin in the past five years.
After successfully finding the sex tape, Barney returns to Ted's apartment to use his VCR.
When Ted considers that the reason why he and Robin never got back together was because she is in love with Barney, he is surprised with Barney's tepid reaction.
Barney tells Ted everything that happened between him and Robin, saying, "Whatever I thought was there, she thought differently", and despite being told that Robin and Kevin broke up, he gives his blessing to Ted if he and Robin begin dating again.
However, before they can watch the sex tape, Marshall and Lily arrive to try to win the bet involving the sex tape (Lily wins if Barney watches it, while Marshall wins if Barney does not).
After scaring Barney with possible images that he won't want to see, Marshall wins the bet when Barney destroys Ted's VCR.
When Robin returns from Russia, she and Ted have the chance to re-examine their relationship.
Ted picks her up at the airport, takes her to dinner at the Brooklyn bistro from the "Pilot" episode, and then home.
He realizes that they aren't going to work out and turns down Robin's consolation that they still have an agreement to get married if they are both single at age 40.
When Ted asks if Robin loves him, Robin admits that she doesn't and feels comfortable with them as friends.
Ted asks her to forget that the past week ever happened.
When Marshall learns that Ted is giving up on the idea of being with Robin in any romantic context, he tells Robin that she should move out for Ted's sake, which she agrees to do.
Robin shortly thereafter moves out, leaving Ted forlorn and alone on the roof of his apartment building.
Some time later, as future Ted tells his children that getting closure on his relationship with Robin finally opened the possibility of meeting their mother, Ted walks out of MacLaren's Bar as all the people on the street walk by with yellow umbrellas.
At their house, Lily, convinced that this is the definite end of Ted and Robin, asks Marshall to pay up on their bet.
Echoing his words at Ted's wedding to Stella, Marshall refuses, smiles and then says "Not yet". 
Robin asks her friends if they would watch her talk show, which airs at 4:00 a.m., and the group reluctantly agrees to stay up and watch.
When Ted turns up, he informs them that Karen (Laura Prepon) has broken up with him, after finding Robin's earring in Ted's bed.
However, as everyone prepares to watch Robin's show, Ted discovers the matching earring of Robin's on Marshall's dresser and mutes the television to confront Marshall, believing him to have sabotaged his relationship with Karen.
As extreme events occur on Robin's show (she starts crying while showing a picture of the gang, she saves the host of the cooking segment when he catches fire, she resuscitates the weatherman after he's had a heart attack and finally she delivers a baby live on camera), still muted, Lily confesses that she has been breaking Ted up with girls who she didn't see passing the "Front Porch Test" — an indication of how they would all live together once they were old.
A scene is shown of Marshall, Lily and Ted in the far future playing bridge (though clearly, none of them know how to play).
Robin returns from the show to learn the truth behind her break-up with Ted, which Lily insists she did not want to happen.
Ted heads into the bar the next day to find Karen waiting, having had the situation explained to her by Lily.
Karen hands Ted a letter from Lily, which contains an apology, and lets Ted know that Lily has prepared a fine dinner in Ted's apartment for him and Karen.
Ted breaks up with Karen anyway after she says Ted cannot ever see Lily again and he imagines what the future would be like without her and Marshall.
Returning to the apartment, Ted asks Robin to be his "plus one" and they enjoy the meal Lily prepared.
They wonder whether or not they would still be together if not for Lily's intervention.
Ted then makes a mock proposal to Robin, asking her to be his "backup wife".
She accepts.
Meanwhile, Marshall wears a nightshirt to the pyjama party to watch Robin's show, while Barney wears a silk suit.
Barney insists his clothing choice is superior, citing the possibility of attractive women coming to his home at night and seeing how good he looks, but then admits how unlikely that is and uncomfortable the "suitjamas" are.
Marshall convinces Barney to try a nightshirt instead.
Barney and Marshall delight in their nightshirts, having a dream about flying together in them.
Barney starts wearing nightshirts to sleep.
A week later, an attractive woman shows up at his apartment at night — but, upon seeing his nightshirt, she decides to leave, much to Barney's chagrin. 
The episode describes Barney as afraid of driving (as of December 2005), but in the very next episode he steals Ted's moving van and drives it into an alley.
In the season 4 episode "As Fast As She Can", he takes it much further and makes a point of getting caught speeding so he can talk his way out of a ticket.
However, Carter Bays did an interview in which he addresses Barney being able to drive:Yes.
It's hard to go back to this, but that scene took place in the past.
In the Fiero episode, what we were seeing was a flashback to before that.
We established that he had a BMW at the end of season one.
Barney can drive.
He was just a late learner.
I'm sure if you put that (in this interview), someone will find a way to prove me wrong.
We had that discussion, but it felt like it fits.
We had stuff in (last week's) episode that we had to cut out for time where Barney talks about how he didn't start driving until late.
So he was learning new things about driving like you can talk your way out of the speeding tickets.
