Hello Redrose123,
It takes courage for you to seek help in understanding the disorder and for your partner to disclose she suffers from BPD.
It is a very difficult disorder to manage, both as the person who suffers from it as well as the "non" in the relationship. I understand how hard it is to deal with the push/pull behavior that is typical of a borderline. It confuses you and leaves you wondering if you are coming or going when it happens. This is due to engulfment and abandonment fears, typically triggered in close relationships.
Is your partner getting help for her disorder?
What you can do right now is read, read, read. Educate yourself on what BPD is and what it will take to be in a relationship with someone who suffers from it. It will not be easy, but by using good communication tools and understanding what can/will trigger your partner it will make the relationship better.
This would be a good place to start to understand the dynamics of being in a relationship with a borderline.

Should you contact your partner? This is hard to say. If she needs space then you should respect that need. That doesn't necessarily mean disappear from her life though. If you think you might be doing something that is triggering an engulfment fear it would help if you can pinpoint that.
Do you think you might have inadvertently did this? What type of contact with her right now do you feel would be appropriate?
