I'm a girl... Is my ex-boyfriend gay?

He very well could be gay. I once dated a guy who had similar things going on with him. He was heavily into religion(although not Christianity) and being right by it. And yes, he would play this card from time to time to avoid certain activities with me(although not necessarily ual ones). Not to mention he would have gay men hitting on him quite a bit, and would be all to quick to fire back bigoted, phobic comments("you f----t", for instance). Being that many gay people can tell who else is gay and that many people who are phobic are often insecure about themselves, I would say the possibility is definitely there.
