I'm working on a story in which a man aged about 30 (who is not the main character) has had an unhappy experience with a woman. They were sort of on-off boyfriend and girlfriend. She would probably have said friends with benefits but he would have liked to mean more her than that. He eventually found out she had someone else and was just stringing him along. The other man also found out and behaved aggressively towards him, causing him to stay away from that area for a while.
My instinct is that the reason this character didn't push the woman to commit herself to him was because he knew, as a man, it was important not to pressurise or guilt trip a woman into doing anything she didn't want to do. Possibly his mother (who is a more significant character and, I hope, a very likeable woman) had taught him that as a teenager.
I think we can all agree that that is how a man ought to think. But if you came across a man with that attitude in a novel, would you think it was unrealistic? Would it put you off him as a character?
This is only a sub plot so in some ways it's not that important but it's just not coming together for me. I like this character, but I don't want him to be unrealistically perfect.
