There's nothing I can't discuss with my daughter, even her sex life in full detail. Doesn't mean we have the closest of mother daughter relationships, it's just not a problem talking, adult to adult on most levels. There are times we do revert to adult child and she does seek me out for advise when she's not going through one of her moods or when she's going through one of her moods, just depends on what kid of mood it is at the time.
Funny thing is, I never really discuss my dating or non dating life with her, at least not in detail, though she does pry, not so much these days though as she knows, I'll be evasive, plus, she's much more judgemental. She used to be bothered my choice to remain single, but, then, I never really discussed much about anyone I dated in detail, she's too much like the mother in these instances and it's annoying having to tell every detail so she can then criticize me for why I'm not introducing the person or looking into a future with the person. She does sometimes like to think of me as one of her friends, like the times she used to want me to always hang out with her and her girlfriends. I was one of the first people she made sure would spend the evening out with her on her birthday bar hopping in Manhattan. Fun for her and her friends, not fun for me, I don't bar hop, but, I went for her sake.

We've gone out dancing a few times since when we've been in the same local, she does love hanging out with her mom. Still, I'm stay the mom when we're out in any such environment and would quickly intervene when I feel the need. Her husband would be there these days, so likely she won't need my skill set.
