ok so i have been hanging out with my lesbian friends reana and michelle a lot lately. they live at michelle's brother's house billy who is married to annah. on random nights billy and annah invite over their friends bobby and jenn, who are dating. i've been over at this house a lot and have become friends with all of them. just about 3 days ago reana told bobby and billy i was gay but they didn't have a problem with it. they said i was still cool. bobby asked why i haven't hit on him yet (jokingly?).

so the other night it was my birthday night party there. some time during the night me and my friend josh i had invited over was watching bobby play guitar hero in the living room. everyone else was gone. now just so everyone knows… bobby is really hot. josh jokes around a lot and he said something like "just cause your a homosexual jesse...blah blah blah."
i said something like "yeah so that doesn't have to do with anything"

then out of no where bobby says, "it's alright dude... i'm bi. i like boys."
i said, "no you are not. you are such a liar."
he said "yeah i am dude. you don't have believe me but i am. just cause i'm with jenn doesn't mean i don't look at boys too. no one else knows so don't say anything."

now why would he say that? it's all that has been on my mind. he told me he was bi and he likes guys and he knows i'm gay. is he trying to do something or what? i'm so confused. please help me. what do i do?
