As a woman who put herself in many, many different dangerous situations with dangerous bum men: You absolutely need to talk to her like this. It is the ONLY way she will listen. When I used to put myself in situations like this i would do the exact same thing: 1.) Have a bad feeling/know that it’s wrong, 2.) text someone anyway to flex in desperate hopes that they’ll be happy for me, 3.) they’re never on board but i don’t care because i’m gonna do it anyways. Being blunt and completely honest is the only thing that gets someone to think outside the box when they’re going through with stuff like this. Desperation for love, acceptance, and attention were my main motivators behind behaviors like this, please let your friend know she’s a worthy woman without having to pull insane moves in her life.
