So an ex-friend of mine is bipolar and has bpd. We were good friends for a little over a year and as someone who also suffers from mental health problems, I felt a connection with her that rarely happens with people, not romantically just as friends.

Throughout our friendship there many times she said things in the moment that sounded mean, even to the point where it would hurt my feelings, but I always just asked her to explain what she meant, and most of the time she didn't mean any harm, she just had little to no filter.

The one and only time that I hurt her feelings, by lying to her which I disclosed to her in an effort to be honest,  she discarded our friendship and has cut off all contact with me. I've respected her boundaries but its been 6 months now and not a peep from her. 

I've heard of splitting but I'm not sure if this is what it is, though prior to this she would tell me all the time that she liked being around me cause i kept her calm. She wasn't doing drugs, any other risky behaviors and she even adopted my calm personality,  so even when I wasn't around she wasn't getting into issues with her parents, friends or people at work.

Im conflicted because I really miss her alot and id like to reach out but I'm also trying to respect her boundaries.  Idk I guess I'm hoping someone with bpd has been through this and can tell me if I should or not.
