RELATIONSHIP ADVICE?!?

[Megan]

Okay, so my bestfriend and I have been more than bestfriends for over 2 years now. He hasn't had girlfriends & I haven't had boyfriends since we met eachother. We started having sex about 6 months ago. After the sex started, I told him I couldn't do it anymore because I was getting too strong of feelings for him that I wasn't getting returned. Later, he told me he was in love with me. We recently got "married" on facebook. After him asking several times if I would marry him when we got a little older & he got off probation. The last few days have gone amuck though. Everything is starting to change. He "divorced" me & "married" another girl on facebook. I really didn't care AT FIRST. But, last night, he came over & we were on eachothers twitters/facebooks just peeking around & I stumbled on his messages to the girl he is currently "married" to. As soon as I clicked it, he completely flipped the computer over on its screen. (obviously has something to hide right?!) He just told me LASTNIGHT that even though he took off the marriage & he hasn't kissed me (I've been sick for a week) in the past few days, it doesn't mean his love for me is any less than it was before.
Tonight, we were on a 3-way call with his bestfriend & he talked to me like complete shit. When I brought up the FB thing & how it hurt my feelings when he yells & cusses at me for no reason & he said "I don't give 2 shits how you feel, actually." Even when I tried to be nice... He still just beat me down. He can't see that he is absolutely killing me. I hate it. I am so in love with this boy, it's crazy. I just need some advice.
