Someone who used to be my FP for a good while hated me the entire time we knew each-other. The entire time we were friends, I thought they were my best friend. They were not. I trusted them with my life, and they hurt me badly. They never told me any of the things they thought about me directly, they only told our friend (now my girlfriend) these things, and I learned them through her. This was many months ago now, and even though I've mostly moved on, I'm still very distressed over the idea of my girlfriend—who also happens to be my current FP— doing the same thing. I'm horrified at the thought that the same thing could happen again. How can I try to move on from this?
