So frustrated with my bf!?

My bf talks to tramps he meets on this stupid videogame website & adds them on facebk. He calls them beautiful & tell them he loves them & they live 100s of miles away. He has a 2nd facebk 2 "separate online & real friends" & ddnt keep it private so i checked it. I was mad since he was still doing those things but he said its "creep them out" cuz theyre "hitting on him". He said this when i fessed up about looking at the profile. Soon after that he changed the name of it so it makes me wonder if hes trying to hide it again. He claims he loves me but we never see each other since hes been at his sister's since november. He gets mad when i question him about things, but apparently it's fine for him to blow up at me for talking to other guys. But im not the one who flirts! Theyre just friends....friends in REAL LIFE. He hasnt been flirting lately or at least that i can see. Of course i dont know what he says in messages & facebk chat, or on that other website.if he wants me 2 trust him, why wont he prove it?
