We are in our forties.
She is married for years. When we go out she is exceptionally flirtatious, provocative towards men and comes onto men regularly. She has been with many and headed home with them on our nights out. She has no interest in our opinions whatsoever on this. Says it's her business and we don't know what hours on in her marriage.
She says her marriage is sexless and doesn't care for him but won't leave because of the kids. I think he is oblivious but when they areout together which is rare she is still flirty and disappears for ages from the group.
It is well known in our circles and village that this is her normal when socialising but my partner now has a problem with me socialising with her.
Thoughts?
