Most Helpful Guy
I dated the daughter of my parent's friends. Not the best idea overall, but I can understand why my parents still hang out with her family. If there was no other connection I might find it odd, but situationally I think there are reasons for it.

My aunt broke up with her ex like 3 years ago and we STILL invite him to all our family functions and routinely have dinner with him. He's just an awesome person, and since the break up wasn't bitter or anything, we don't feel like we have to pick sides. We did however ask if it bothered my aunt and she seems to have moved on and treats him like a friend, so that's why we don't think we're doing anything inappropriate by continuing to have him as our family friend. Me personally if it were my ex, kind of the same situation, but the only thing I wouldn't feel comfortable with is family talking about my new private life with him b/c that would be none of his business. We don't actually talk to my aunts ex about her life except to say she's fine or doing well, or just cordial stuff, but no details.
