Summarize this article in one sentence.
It's difficult for anyone to suddenly view someone they used to love as a mere platonic friend. Some people simply can't do it. If your ex boyfriend is showing any of the following behavior, you may want to consider giving him more time to move on: Calling or texting you regularly without a specific reason Constantly talking to your friends Making inappropriate, overly-intimate jokes or references Bringing up things about your old relationship Touching or brushing up against you, accidentally or otherwise If you've gotten a new boyfriend since you broke up with your ex, the situation becomes substantially more complex. Even the most understanding boyfriends will likely be a little jealous at first. Some may never stop being jealous. The best you can do is to clearly and calmly explain that you're not "into" your old ex. Explain to your current boyfriend that you love him only and that you're just looking for harmless, inconsequential fun with the ex - nothing more. Make it very, very clear that you don't (even better if you say that you can't ) think of your ex in "that way" any more. Your ex will also need to have this conversation with his new significant other, if he has one. Don't do anything to give your new boyfriend any reason to suspect foul play. For instance, don't stay out later than you said you would until he becomes comfortable with you hanging around your ex. However, if your new boyfriend is acting very paranoid about your new friendship (constantly texting you for updates while you're hanging out with the ex, etc.), it's OK to dress him down. If you've given him no reason not to trust you, you deserve his trust. If you want to be friends with an ex, do not do the things you used to do when you were dating. If you do, you're inviting inappropriate feelings of infidelity (if you have a new boyfriend) and setting yourself up for a "relapse" and possible heartbreak. Start anew - take the opportunity to experience new sights and activities as friends. Avoid locations you used to visit - don't go to the restaurant you used to get breakfast at or the bar where you first met. Refuse to participate in the activities you used to do together - if he invites you to feed the ducks at the park like you used to do every Sunday, tell him you'd rather meet for coffee. Initial interactions with your ex can be tense, but, with luck, this will soon give way to cordial politeness. Once you've let your guards down, however, you may discover that one or both of you still harbors emotional wounds. Deep-rooted feelings of betrayal and heartbreak can take time to emerge. If you encounter these things, they may be signs that you and your ex aren't ready to be friends yet. If you get sad or angry around your ex despite both of you projecting a happy exterior, or if you always feel that you want to say more to him than you can politely say, your problems might not be sorted out yet. Take some time off from your friendship. Conversely, if he seems moody or irritable or he won't talk to you about anything meaningful despite his willingness to meet, he's probably thinking about your old relationship and/or the things that led you to break up. You can ask him if he is, but be warned that this can push him towards irrational anger or sadness. Over time, you may grow close to each other again. Take things slowly - only allow your friendship to mature when doing so seems natural. Establish boundaries for yourself early on - things you won't do or talk about with this person - and only lift the boundaries when you're sure you can trust him Equally likely is the possibility that you find you don't like being friends with your ex! In this case, just stop hanging out with him, but be warned - he might not give up as easily. Awkward feelings of clingy-ness are, unfortunately, a very real possibility when trying to start a friendship with an ex.
Know the signs that show he's still into you. Explain things very clearly to a new BF. Don't fall into old patterns. Make sure your ex and you aren't still hurting. Allow your relationship to gradually deepen.
