is there anything I can do, anything I can say, I just need some advice as to anything that can make things a little easier for her.
The lessons on Validation, JADE, and SET are very useful for learning how to deal with BPD. I've found that many of the things I used to do to help my BPD wife actually made things worse. Often when we get wrapped up into helping someone else, we adopt codependent behaviors that are counter productive. This is something to look out for. The most important thing you can do to help your BPD girl friend is take care of yourself. What kind of support do you have for you? Do you have someone you can talk to? Living with someone with BPD is challenging. Few people can do this and stay sane without some support.
she see's her parents often but they don't have a very open relationship where she is comfortable talking to them, would it be helpful for her to talk to her family too?
Talking to her family is a decision she has to make. It's probably not a good idea to push this.
