What the hell with this guy now??

I work with a guy who's got a similar sense of humor to me dot-dot-dot we've got to know each other over time and he basically indicated to me recently that he sleeps with guys. We continue being friendly and then one day he said something that must have thrown me off because I finally asked him if he identifies as gay or bi. He didn't answer right away and then said bye but he really needs a woman in his life.

Here I thought he was gay all this time and was talking to him as such but now find this out and he seems to be kind of interested in me some things he said. Going to be mean but I don't want to be with the guy who's been with a lot of other guys and is always looking for guys it seems....wth? Is this guy really eally just gay and can't admit it?

Sorry posted this in the wrong forum
