I've been with my current boyfriend for a little over 3 years on and off. We fight constantly, and break up what it seems like, every other day. I've gotten to the point right now that I don't know if I love him anymore. I'm used to seeing him everyday and now I don't see him for weeks at a time. We used to be inseparable and text each other constantly. Now I'm lucky if I talk to him once a week. I can't stand the person he's become and I don't know if I want to be with him anymore. I just don't think I can take it. I've tried everything to get us to work but I think he's cheating on me. I mentioned that we should try and take a break but he freaked out and said I just wanted to break up with him so I could go sleep with other guys. What should I do?

Break up and go sleep with other guys.

Follow what is in your heart! If your not in love with this person anymore, I know it's hard but move on. Sounds to me like that's his plans anyway. He just got mad because you beat him to the, "moving on until he was done with you part." Sorry but he sounds like a immature jerk.

You did not list one POSITIVE thing in your post about this relationship. So... seems pretty clear what you should do.

Ya break up with him, there's nothing left of the relationship you guys once had.

So in 3 years there was nothing that makes you feel happy when you remember?
3 years is a long time. Do you think he still loves you? He might have any problem that is bothering him.have you discussed things? I have a feeling that you too are going wrong somewhere not just him. A relationship is reciprocal and both of the partners should work on it to make it strong.
One advice from me: don't start creating feelings or dating another guy before closing this relationship. You are going to hurt yourself and him more than you can imagine.take your time and don't go directly into another guy's arms.
And remember 3 years are approximately 1/25 of your life.he is a part of you now.dont make decisions that you may regret in the future.take your time.
