What kind of questions...

I find that hearing about his other relationships can be very revealing. Not just with other women, although hearing about the ex-girlfriend/previous sub/first wife can be pretty useful, but also his relationship with his kids, with his parents, with co-workers. One guy that I liked a lot, in retrospect, gave me quite a bit of info about himself that I might have paid attention to - very judgmental about co-workers, not thoughtful of his parents, selfish with the ex-girlfriend. No one thing would have been enough to raise red flags - it wasn't pathological - but when you put them together it was a pattern.

not thoughtful of his parents,

In my personal life experience i will NEVER EVER be with someone who is not thoughtful of his parents. ESPECIALLY his mother.

I have often just said "so tell me about your mother" in early stages of relationships.

I think the other thing that is important here is to listen to the questions they ask you.

I'm sorry to hear all the people who have said that Dom's aren't good question answerers. I actually love questions. They speak volumes about what someone knows or where they are coming from.
