Hi Chicopee and a warm *welcom*
The pain you're going through sounds intense. The highs of that relationship were probably pretty high, and the lows sound pretty low. That's a lot to experience.
A lot of times, making sense of a breakup where BPD might be involved ends up being less about making sense of
them, and more about making sense of
us. Turning the spotlight on ourselves is sometimes a novel thing to do. It's so easy to be distracted by "why did she do X, she said A but then B, she said I was the love of her life and then treated me like trash"... we can spend time on trying to "decipher" them when the real puzzle might be us, and what led us to that relationship.
