So I’m currently trying to learn what I can about BPD, as my bestfriend (Who I recently reconciled with) has been diagnosed with it during the time that we weren’t speaking. She wanted to give me a head’s up, as she felt like it would be beneficial for our future relationship. She also told me about having a favourite person, and that for her, that person was/is me. Now I’ve done some reading, but I wanted to post this here for some further advice. Firstly, what’s the best way to respond to this?
