Hello, I am 2 days out from a split with my ex. She told me in the beginning that she had symptoms of BPD, and I learned about it so I could be informed. Everything was so good - I had never experienced deeper emotional connection, never had more vulnerability, never had such unbelievably honest/direct/clear/compassionate communication. I was (am) so in love with this woman. She knew all of me. Literally all of me.
One day she claimed she was more vulnerable in our relationship, and that she felt like she didn't know me, and that she knew I didn't trust her. She said she loves me more than she has ever loved anyone, and she saw a future with me, but now she just can't see it. It all came out of the blue - right after she had some unexpected results from a doctor appointment. She says none of this is related to the stress of the appointment. I am devastated. Utterly broken - I have never felt this kind of pain.

I've been reading through a few threads here, and I've seen the topic of "recycling." Is this something that is really common? Does it happen in most cases? I'm anxious this will prolong my grief. I've made it clear that I'm closing the door to this relationship - is this a surefire way to make her try to get back with me? Is there anything I should avoid saying or doing? Any advice is welcome. Thank you.
