Hi Dlusko7 and

Wow, lots of moving parts in your life right now. I can understand you have plenty of reasons to want to make things work, even though it's difficult.
Just a few questions so we can have a better grasp of your situation:
How long have the two of you been together?
Who has what kids -- all yours, all hers, both? And how old are they?
Sounds like both of you were married before -- how long were those marriages? What ended them?
Good to hear you have a counselor who is aware of BPD. Is your W diagnosed but not accepting the diagnosis, or undiagnosed?
My H's kids' mom has many BPD traits but no diagnosis as far as I know -- hasn't necessarily made it easier. The good thing is that this group can really help with sharing new (and often unintuitive) tools and skills for more constructive communication and relating with pwBPD.
Fill us in a bit -- we'll be here for you;
