Hi Brokenhearted59,
I'd like to join

fromheeltoheal and welcome you to bpdfamily. I'm very sorry to hear about your breakup. That is so painful. I can relate very much to your situation, as I was in a very similar one. Fortunately for me, we broke up before I could move to another country to be with him, so I was at least spared that stressor on top of the already obvious one. My heart goes out to you, because I know how hurtful it is to experience the abrupt turnarounds and changes in feelings of someone with BPD. It's a real shock to the system.
You've found a great place for support. The members here really understand what you are going through, and the site has tons of tools and resources that will help things get better. Things really do get better—they certainly have for me, and they can for you, too. These breakups tend to hurt much more than "normal" breakups because the connection between the pwBPD and us can be very emotionally loaded. That was definitely my experience, and I needed help (therapy, no contact, this community) to recover from it.

Fromheeltoheal linked some very important information that can help you understand what you have been through. I found the article on "Surviving A Breakup When Your Partner Has Borderline Personality Disorder" especially enlightening when I first came here.
Aside from therapy, do you have a support system around you—new friends perhaps? How long were you together with your partner?
Keep writing. It helps to tell your story. We're here for you.
