I'm confused about my friend's sexuality
I have a friend who I have known for about 4 years. He's in his mid 40's, he is divorced and has kids and has a girlfriend. The point is that every time I go over to his house his always making comments that indicate in a sly way that I'm gay I wanted to know if he could be gay? He always says things like I have a beautifully soul and I'm caring and tells me stories and somehow they end up being gay. He also brought up in conversation about gays and I told him just to see his reaction I told him I hate gays. His response was very defensive, and also another time I text him telling him that I wanted to ask him something important (if he was gay) and when I went over to his house (I think he knew) all he talked about was hot chicks trying to pick him up, and how he was in a committed relationship, and when I was talking to him in conversation his girlfriend rang he didn't answer the phone! I was like What?
I'm so confused and there was also another time where we were watching TV and he point out every person in the show gay or puts on movies and somehow one of the characters in the movie ends up gay and there was a movie where the background song was (I don't know if anyone knows this song)" I want to know what love is I want you to show me" and while this was on he was singing the song and just so happens he looking at me while he was singing this song. So talk about being pressured and awkward! And before he told me he had a girlfriend on the day I was at his house he was sitting close to me about a chair away and I told him a story about a friend of mine who told me he was gay and all he wanted to know if I was gay. I told him I wasn't in to that and he was like “Oh!”, and moved to the other seat and then said that he met his current girlfriend and ever since then all of the above has been happening.
What should I do? Should I ask him is he gay or no and what happens if he says his not gay or bi and says he has a girlfriend and continues to do this?
PS. Just a note: I text him telling him if it bothered him if I was I'm bisexual and he didn't return my text. He also says to me that he has a gaydar and can tell if someone who is gay?? What do you think? Do all of these things point out that he may be confused? He also asked me once what type of sound I make when I orgasm? Yes, all heterosexual males ask each that all the time!
