I'm 31 with a boyfriend a few years younger. We've been together just under a year. Recently I asked him 'who was his first kiss' and he completely refused to talk about it. It was just meant to be a random conversation - I know it's a big moment in people's lives so I wanted to know. But the fact that he is hiding it so much is making me feel uneasy. He says I don't know them, so if it's just someone random why wouldn't he say? He says he has nothing to hide he just doesn't think it's important and so he doesn't want to talk about it. He said he doesn't want to talk about his past and then later apologised and said he will try and be more open about his past with me when I ask in the future, but he says it means more to me than it does to him. I just feel so hurt! As far as I know nothing major has happened - so what wouldn't he want to talk to me about? I understand he has a right to privacy but when he talks about settling down and starting a family with me it makes me anxious when he can't answer a simple question like that, and not want to talk about his past with me? I said to him if he really believes there's nothing I should know then we can leave it at that and draw a line under it. How much do you know about your partners past? Is it really relevant?
