Yep, excellent responses from all. I too was wondering if either your roomie thinks you might be gay and is figuring it out, or if he might be gay and wondering if you are too.
Well, none of us were there, so we can't tell. Be safe first of all. But be aware of the possibility that he might turn out to be a friend, or even be gay and closeted himself.
Never linger too long with the ignorant,
throw stones at their talk.
Walk only with the lovers,
the mirror of the soul gets rusty when
dipped in muddy water.
