I recently met a wonderful woman with BPD. Hit it off great. She is amazing in every way. Very intelligent ( emotional and general), very open and communicated effectively, very beautiful, self aware, and our personalities compliment each other very well. 
Things progressed very fast, but never felt rushed. She was very easy to talk to. I sensed a little codependency, but never problematic. I offered reassurance when I noticed. She seemed to greatly appreciate it. We were both very infatuated with each other and she even confessed to taking for me. Everything was very comfortable feeling, so I reciprocated my feelings. Not something I would typically do this early in a relationship, but they were genuine. I truly felt like I saw her. Not symptoms of a disorder, not the things she said. Her, at her core. And I loved what I saw. 
The next day, I was discarded with a lengthy text. She mentioned my love confession being part of the reason. And that she was splitting, which is a term I hadn't heard until then. 
I've been reading on the subject, trying to make sense of the situation and have a very basic understanding now. But the whole situation is very confusing. I'm not sure I've ever been more confused.
Really, I'm just looking for some insight. I assume, I'm now on the bad side of her splitting. Is she likey to reach out? Should I try to reach out? If I am on the bad side of splitting, should I move on? Dating someone with BPD seems to have a completely different set of expectations than with people without. I truly believe I can handle the hardships that follow dating someone with BPD. But maybe I'm naive. I have no clue. I've never met someone who has ALL the characteristics I look for in a person. And she does.
