Input: We've been friends since we were seven. He's always been extremely flamboyant and feminine. I didn't start thinking he was gay until we got to middle school. He really acts very gay, not even just in personality. I remember in 8th grade there was an incident where he kissed a substitute teacher who was male. So, I've generally for most of our friendship, saw him as gay. It's not like I rubbed it in his face or told other people. I just always thought that he was homosexual. We're in the same college right now and we requested to be roommates. So, we live together. He invited this girl over and she kissed him and told him that she liked him, I was astounded. He said that he'll think about it and I asked him about it. He was extremely offended and hurt when I told him that I thought he was gay. He told me that he's straight and I was just blank. It's been extremely awkward between us and I just don't know what to tell him. I feel like an asshole.
