You need to end it with her

I’m going to be that asshole, but i don’t think she was abused by him. Why is she still constantly talking to him in the first place? Why is she going out of the country to visit him and his family?

Based on this information, it seems like she’s cheating on you. I mean come on! A vacation out of the country with his family?

Why would you put up with this? Both your GF and the ex are scumbags

I know I’m an asshole for doubting her abuse. No victim would ever do what your GF is doing
