give thoughts to friend or stay silent?

A

Hey! So recently one of my friends has gotten into a sort of FWB(it’s complicated) relationship with a junior (we are freshman). He goes to a different school and has a car, etc.

The first (and only) time they met up, they made out in his car and it escalated a little more than that.

I’m worried because she kind of likes this other guy and I think she may be doing it to make him jealous? Even if she’s not, I want her to be careful and not take things too quickly. She’s not the type to take advice super well, she’s somewhat stubborn and jumps to conclusions.

What should I do?!
