You're contradicting yourself. He is now straight, based on your argument. I does not depend on what he does from here.
As I said before, if someone goes back and forth between the genders, they are bisexual.
We only know of one change this person has made. If they don't make another and stay with women, then he has become straight. If he continues to see both genders, he is bisexual. If he goes back to only being with men, he will be homosexual again. As things stand, he is either heterosexual or bisexual at the present time.
I'm pretty he still considers himself gay. And that's all that matters- his opinion on his sexuality. He's not accountable to anyone else. He's gay if he says he is. Or bi. Or straight. There are no prerequisites that he has to fulfill.
Is that how everything works in your mind? Are you whatever the hell you think you are?
No wonder you're so ridiculous all the time. You think whatever you say is just the way things are. You don't need a reason for anything.
Wow. Thanks for the laughs. No, really. I just about busted a gut there.
