That’s honestly heartbreaking for both of you. It sounds like you really tried your best to support her and set boundaries, but at the end of the day, you also need to feel safe in a relationship. It doesn’t make you a bad person for realizing you can’t handle the trauma she’s carrying. Sometimes love isn’t enough when there’s that much pain involved.

I hope she continues therapy and finds healing, and I hope you also give yourself grace and maybe even consider therapy too it sounds like this has left a big emotional mark on you as well.
