It sounds like you already know the answer, Rose, at least that's what is coming across in your e-mail. If the majority of the time you aren't happy in a relationship, and it's causing you a lot of stress, that's a serious tip-off that it's time to break up. You will still have special memories of the good times, and there's a chance (albeit a slim one) that you two will be able to be friends after the breakup. Staying together just because the two of you have been in a relationship for a while is not a good enough reason to stick it out, particularly when you feel bad about where you're at.

Have you clearly told your guy that his behavior is causing you pain and making you pull away? It's possible that he doesn't fully understand, although we are going to assume that you've already talked to him and that it hasn't helped much. If there is part of you that wants to make it work, it may be worth it to explain that his jealously is driving you away, and that if he can't trust you and stop fighting, then you will end things, immediately. But it sounds to us like you're already at the breaking point, so the best thing for you would be to kindly tell him that it's over.
