How to deal with our unhealthy relationship?

I dont have a healthy reletionship with my boyfriend; well so I am told. we cheat on eachother all the timee, we tell eachother that were going to change, but something always keeps happening. lieing, cheating, just things that shouldnt happen. BUT when its just us two. hes amazing. I dont know how I could go on with out him!!!
help. I need helppp! I love him.

talk. if that doesnt work threaten to break up

what I think both of yall needs to do is just first sit down and talk about wats happening if that dosent work then I think that you guys are better off as just friends, or just need to take a break from each other

Break up. Sounds like you don't honestly love each other anyway.
And stop sleeping around with other people all the time. What if you got pregnant. Therefore creating a human life with a person you didn't even love. Would an hours worth of passion really be worth that heart ache? Would it really be fair to do that to yourself and the baby? No. It wouldn't. And it sounds like, you're young and not ready for a REAL relationship., just yet.
