It certainly sounds like you've had a lot to deal with. Living with someone with BPD is indeed a draining thing, especially when they refuse help. For while, when my H was stressed about work, he managed to turn it all around to being my fault. When he gained a more solid emotional footing, he had the self-awareness to tell me that was exactly what he'd been doing. Easier to turn things on me than blame himself. PwBPD tend to have very strong feelings of shame and guilt. Not having the maturity and tools to handle it, they'll often turn that shame and guilt outwards, projecting it onto their loved ones. Not easy to deal with at all.
I'm glad you've been reading posts and have been looking at the tools available here. The tools aren't always easy to implement at first, but they can make a real impact. Are there any you've read about that you think might help your particular situation?
