Best guy friend troubles... :(?

Okay, so my best friend, Brandon, and I have been friends since over a year ago. We got really close really fast, and told eachother everything. He's been there for me through so much. We've litterally gone through hell and back with eachother. When we stopped being friends the first time, It was because of his gf he was dating. She was a psycho, and forced us to stop being friends. But then they broke up and like three months later him and I started being friends again, and it felt like we went right back to what we were before. And he started saying he had feelings for me, buut would also flirt with other girls and i'd find out. & Like he was "married" to some girl on fb too, and siad he liked her too. And I told him i didnt wanna be mindfucked, so I stopped being his friend, but then I missed him and felt stupid so I went back to being friends with him. And like, he still tells me i'm his best friend, and that I'm the only girl he actually loves more than a friend, and he gets mad at me for liking someone else. Like, vishiously mad. Yet, He tweaks out on me for getting mad that he likes other girls too. But I'm a good person, so when those other girls **** him over I'm always there for him and let him vent to me. But todayy with my wholeuncle dieing thing I wanted to talk to him about it beacause hes my best friend. And I ended up writing him amessage longer than this one just venting about life. and we said like two things back and foroth and he started tweaking outt. not on me, but about life. andd the last text message he sent me was "I dont need ****. I need to move out of this ******* state. I'm sick and tired of everyone here. I'm gonna let you go because I'm not really in a good mood now. Its not because of you either so don't think that". its weird cos he didnt even say "i love you " like he ALWAYS does. but i replied backand he didnt reply. yet hes on fb, and he's going and liking everyones miserable status's. but hes still ignoring me. and it makes no ******* sense, but he went from being married to that bimbo, to single. and his statuses are about how hes "done" with everything. But hes not venting like usual. Hes like, not even acting like himself. :(:(
