I broke up with my gf about a month ago. She's undiagnosed but my therapist says she has BPD. 

She always said I was her soulmate no matter how bad things got. 

My question is, does anyone think it would be possible for her and I to be friends in the future? 

We're currently in No Contact so I can't ask her this. But I really miss her and think about her everyday. Also, I've heard lots of stories where someone's partner with BPD moves on quickly and dates other people almost instantly. But I don't think she's like that. I know she really loved me. And I really loved her too, and still do. She's a very shy and reserved person but very bubbly one to one.

I have so much guilt over ending the relationship and how I ended it because I think it happened so fast for her. I'm really worried about her health too. I've been wanting to message her best friend but my friends tell me not to. 

So yeah, since I was her soulmate and I broke up with her, is it possible to be friends in the future? Or is the probability very low? 

When I was breaking up with her, she actually did say that we can't be friends because even I said early on in our relationship that we can't be friends because we have too much chemistry. 

I just really miss her because I never felt so connected to anyone before and we shared so many interests together.
