I am sorry you've had a bad experienced with Her, @
DanM!! Unfortunately i can't tell you for sure whethe ror not she had BPD or not since I'm NOT a professional. My advice would be to continue with your own Life. You can only do so much to help Her after all. It is HER choice whether or not she wants to work on herself... so please, definitely focus on Yourself. You did what you've had to do and you've tried your Best. That's ALL you could do, really. If you feel like you're better off without her, then definitely continue your own Road and Journey in Life. Sending many safe, warm hugs to BOTH you and HER, @
DanM, your Family, your Friends and ALL of your Loved Ones! KEEP FIGHTING AND KEEP ROCKING YOU BOTH NO MATTER WHAT HAPPENS, OK?

Hopefully she'll be able to acknowledge that she NEEDS to work on herself and she'll be able to better manage her Behavior and her Mood. Sending many safe, warm hugs to BOTH OF YOU! KEEP FIGHTING AND KEEP ROCKING YOU BOTH NO MATTER WHAT HAPPENS!!
