You are going to go through a recovery phase, you will be confused and trying to put the pieces of the puzzle together, trying to put the answer to WTF just happened. It took me nearly a year to recover, I'm fully recovered I wouldn't ever talk to my ex again, I do think about her. Once you've purged yourself of the toxicity she put into you, life will be back to normal. You have been now programed with a crazy meter, once you've been with a BPD you can see the triggers, you can spot the crazy before getting involved with them. When I encounter women I try to find out what their family life is/was when she grew up if I don't like what I hear I quit getting to know the woman.
BPD women can be "F"in vicious, my ex locked horns with me she wanted to see me pay for breaking up with her she wanted to ruin my reputation she caused me a lot of trouble I'm just glad I never ended up behind bars. The good times we shared, the things I did for her etc it was all gone she forgot all about that. She's with a NPD guy he's got issues, she "claims" to love him, after being with her for 3 years he's a wreck.
I don't think BPDs ever forget about you they are like a bad rash that never goes away. BTW my ex claimed she tried committing suicide, she would go see a shrink.
