My girlfriend has BPD and our relationship was perfect in the beginning, she was just as clingy as I am, and she always wanted to be apart of my life. We met online through a friend of mine who met her online. I flew to her country and spent time with her and we've been mostly happy since. 

About 6 months into our relationship she left me for another guy, it hurt of course but it wasn't like a 5 year relationship or anything. A month later she came back and asked if I wanted to be together again, and I agreed.

Fast forward 4 months and I find myself waiting hours for replies, we never do anything together, and she always just wants to be alone. Its so hard not knowing how or what I can to do help her (since shell just tell me to can it whenever I ask :P). She means the world to me and I don't know of its just her personality, something going on, or her BPD. She always blames it on her disorder but I just want some insight as to if that's really it. This all started since we got back together.

Her parents refuse to help her treat it and they're in complete denial she even has BPD. They wont even help her get a therapist, and shes too anxious to do it on her own, and I'm hours away. 

TL;DR Whats your guys' advice for someone who has a distant girlfriend with BPD? What can I do to be her fp?
