Hi luckyclover,

I'm sorry to hear about your breakup. I know how devastating it can feel; it certainly felt that way for me. You have come to the right place for support. We have lots of tools that will help you get through this, and members who understand. Hang in there, you are definitely not alone.
Was your ex-girlfriend diagnosed with BPD? How long were you together?
The rapid changes in your ex-gf's feelings sound very familiar. That is common for someone with BPD/traits. It's very hard to cope with, especially if you were very focused on her happiness, as many of us were. She may or may not try to re-engage. If you follow the lessons on this site, if she does try to re-engage, you will be in a much better position to decide if you want her in your life.
Here's a link that helped me tremendously to understand how to let go with grace:
Surviving a Break-up when Your Partner has Borderline PersonalityIt sounds like you have spoken to some therapists? That is a really good move. I know it helped me a lot after my breakup. What else has been helping you get through the last 2 months, lucky? For example, do you exercise, eat well, and get enough sleep?
Again, welcome to the site. Keep writing, and let us know how we can support you. We are here to help.
