My daughter is 15 and very responsible and mature for her age. Her best friend has had more than ten boyfriends in a short time, while my daughter has none. My daughter thinks there is something sad and disturbing in the way her friend flits from bfr to bfr. Because of this, my daughter has withdrawn slightly from her friend, and hooked up with other girls, who share her view about having loads of bfrs. The mother of the girl with many bfrs, has now started a whispering campaign about my daughter "being jealous" of her daughter, hinting that if my daughter can not "be happy" for her daughter, she is no friend at all. Considering that we have treated this girl as a member of our family, paid for holidays for her etc, I find her attitude extremely hurtful.
The mother is a single parent who does seem to live her life through her daughter, but still...
I have now told my daughter that I do not want her to have any contact with the girls mother, though I'm quite happy for her to be friends with the daughter.
Am I being unreasonable?
