Summarize this article:

If your boyfriend is making you jealous and isn't paying attention to you, talk to him about it. Don't accuse him of anything, but try to have a mature conversation about how it makes you feel in the relationship. Catch him at a time when he seems calm or relaxed -- you don't want to bring up a difficult subject when he's already had a hard day. Relationships are partnerships, and they involve compromise and sometimes sacrificing things for one another. If you feel you give and give and your boyfriend doesn't treat you well, it may be time to consider ending the relationship. If you feel your guy is being a little hands-off or distant then tell him that you don't feel cared for very well. Encourage him to be more affectionate and passionate when you're together, instead of trying to bring it out of him with manipulation. If you think he might be bored in the relationship, get more creative with your activities. Do things that he really enjoys and keep the relationship at a steady pace. It could be good to ask him if he's bored with you in particular or just with how the relationship is going. That will help give you a lot more insight on how to spice up things. If you feel the need to act a certain way to make your boyfriend jealous, it's a bad sign. It means you're not communicating openly and your relationship is in bad shape. Even if you're successful in making your boyfriend jealous, you run the risk of your boyfriend ending the relationship instead of becoming more passionate. If you want him to pay attention to you, tell him you need him to be more committed and you can't last in a relationship that's only one-sided. If your boyfriend doesn't pay attention to you, it's likely he's lost attraction to you or has become complacent in the relationship. Evaluate the relationship and the type of guy he is to figure out if it's worth working things out or if it would be better to break it off.
Remember communication is key. Explain to your boyfriend that you feel neglected. Stop trying to manipulate each other. End your relationship if it's going poorly.
