Okay, so Brett* my boyfriend and I hav been together for a good amount of time. I love him with everything I have, and he says he loves me. This past summer, he started to act more like an a-hole than ever. He used to call, and he'd tell me about this girl he thinks is hot, and how he likes her. I dont know...but that got me pretty badly. Then, it started with the phone calls just to tell me goodbye, and he's walking out the door and I wouldnt hear from him in 3 weeks. In October, i found out about this girl who he'd been seeing more of, and he slept at her house, etc. Now, he started to blow me off for her....but still in all, I tried not to love him, even though I wanted him sooo badly. Meanwhile, we broke up for a month, and then he came crawling back. And since then...one day it's like "I love you" then the next day "we dont belong together" and then back to "I love you."

-So here I am, hurt and confused. We've been together for 2 years, and I would hate to break up over this. I've gotten no explanations for the way he's acting...except for the girl thing which he told me he was "kidding" - but obviously it's bullshit if it went on everyday for like, a half hour. I have ppl tellin me to stay with him, most importantly myself, and then people saying to dump him, which I want to do...I think?

I really need more opinions.

Thanks!
