What am I supposed to tell her?

Bold & Brash

My best friend just got broken up with but her 7 month boyfriend. Shes really hurt and I understand that but she idnt going about it the right way. Now shes talking to an 18 year old, a 19 year old, and a 16 year old about having sex with them. We are both 16 year olds and sophomores in high school. I keep telling her that sex isnt gonna change or do anything, not to mention it's illegal for minors to have sex with legal adults. Its disgusting that they're doing that and she needs to respect herself more. I keep giving her advice but shes not listening or taking it, do I just leave her to be her??? I'm such a mom towards my friends and I care about her but nothing's working
