I have a friend who, for anonimity's sake, will call "JD". Well, JD's asked me for advice about a certain aspect of dating: What should be expected about the person you're dating when his/her new favorite subject of conversation is talking about everyone that came before JD?

When asked this question, I didn't know what to reply, because my two ex-girlfriends who surpassed their first trimester with me didn't really mention their boyfriends; yet the fact that they didn't doesn't tell me if it was a good idea or not, because: 1. I have no standard for comparison, and 2. JD's date is over 21, and the aforementioned exes of mine weren't.

So I ask anyone who's bored enough to read up to here: Is it a good, bad, or irrelevant sign that your boy/girlfriend decides to give you a VIP tour of his/her past?

Dating your friend's ex, or your ex's friend, is extremely frowned upon in America's 18-25 society. In your opinion, is it a reasonable judgement or is it just rampant jealousy?

I agree with the latter choice. Then again, I can't even buy myself a drink, so there are quite a few things I don't know, which is why I'm forwarding the question to YOU.
