Hi Langland11,

I'm sorry to hear about what is happening in your relationship. I can understand your feelings. I know I'd be wondering how my boyfriend/partner could say one thing one minute, then act in a way that seems to completely go against what he just said. Very confusing. And I experienced it, too.

If your girlfriend has BPD, these kinds of impulsive turnabouts are likely to continue indefinitely, unless she decides to get help managing her behavior. You can learn tools (such as communication, boundaries, etc.) to improve the relationship. Just keep in mind that it takes a lot of commitment, work, and patience for both parties.
The evolution of a relationship with someone with BPD can be very intoxicating, so that when it shifts into another mode, it can feel quite shocking to the partner. That's what happened in my relationship, and I ended up getting physically ill at the very end after one particularly shocking "change of heart."
Here is some info. that might help explain what often happens in these kinds of relationships:
