SD dresses way too sexy and has a boyfriend she spends way too much alone time with. It's the fault of BM who thinks her daughter is her friend and teaches her how to dress and put on make-up. BM also talks to SD about all her sexual escapades and her experiences stripping. BF has no backbone when it comes to SD and never sticks to rules about these issues or punishments.
I can't let it lie anymore because it's to the point where my family does not want her attending family functions and I don't like taking her anywhere. BF is disturbed that my family doesn't want her around (which is not just for her sense of style, but nasty attitude as well) and it's causing problems between us.
How can I reverse the damage done by her parents? I don't want to be a step grandmother before I'm 30, but it's looking like that could be very possible if nothing is done.
