I think your friend is wrong...

Having been divorced, I know that men I dated when I reentered the scene were also somewhat curious about my divorce, mostly to ascertain whether I still had feelings and/or baggage that would later reemerge in a detrimental way.

I wouldn't suspect your bf of that unless he himself gave some indication that he is ready for marriage. He probably just wants to know where you stand with your past and how it is going to affect your future relationships.
