I'm sorry for what brought you here but I'm glad you're with us. We help and support each other here. From what you have said I think you belong here; you will fit in; your situation is like a lot of the other members.
As trite as this sounds, the short answer to your question is that as long as at least one of you has hope, yes there is still hope.
There are communication skills that will minimize the behavior of someone with BPD and these have proven successful for some of the members here. My relationships have changed because of learning to communicate in a healthier manner. Stopping argument before they begin or escalate to the point where things are uncontrollable has been one of the greatest assets that I've gained here.
What do you think is the right direction for you, and the best kind of help you hope to get here?
I know your life is difficult now, but knowledge will help you make the right decisions. Please read the articles and workshops - they will give you some good skills at communicating. I look forward to reading more about your situation when you're comfortable writing about it.
