My boyfriend is very secretive about past relationships, and doesn't talk about them much. From a little detective work, I have found out that he dated a woman 14 years older than him when he was 20 or so. I also asked him about another of his exes once because she is always hanging around, and he answered but thought it strange that I asked. How can I find out a bit more about his past? I mean I'm not even sure why I want to know, but I feel like I can't really know someone well until I know where they've come from.
