I’m jumping-in late and haven’t read the posts above. Your question struck a chord with me, because of my experience with a long-ago, former fiance. I have little doubt that the guy was gay but in deep denial. The signs:
- When we were out in public, he’d check-out men. He’d stare with appreciation. When we were sitting in a restaurant, his eyes were usually off me and searching the room. If he saw me noticing, he’d quickly try to cover by saying he liked the guy’s jacket, trousers, etc.
- He never gave me any compliments; even when I dressed-up and looked nice, and other people said so, he didn’t care. But, he was fixated on his own appearance. He spent a great deal of time grooming and primping, and he wanted frequent (i.e. daily) compliments from me.
- He was borderline-flirtatious with men, often commenting on their looks, hair, or clothing. Women tend to greet each other with compliments; it’s not unusual to see a friend, or even a stranger, and tell her that she looks great, or that her shoes are pretty. Men don’t seem to do this with other men, unless they’re flirting.
- He was homophobic. In my own mind, this is the acid test. Heterosexual guys, secure in their own orientation, really don’t care whether other men are gay.
- He eventually married a very mannish woman who looks like a guy and has a deep, masculine voice. I know nothing about this person, but she does seem to be my ex’s type.
There were other, more intimate signs that I’m not comfortable mentioning.
