hi dharmabum,
Your post may soon be moved to the Relationships section (it is now in Children, Parents or Relatives with BPD > Son/Daughter with BPD), but thank you for posting.
I forget sometimes, that my BPD'd mother and my wonderful/nice/loving codependent father, do love each other. I do understand the "Fight to the Death" need to be right and the very controlling nature of this mental illness. I didn't understand it for years, it was just annoying and/or very damaging to me as as a child. I am now a grown women with step children/step grandchildren of my own, so I suppose we can overcome anything, even an invalidating mother. If you do decide to have children with this women (or man, if that is the case, hard to tell from your handle/post), you will need to be the stable parent for your kids. My Dad is great, it is maybe a gift that I do have a great relationship with him and it could be because he was always trying to get away from my Mom with me and my 5 siblings - or she was driving us away (I Hate You Don't Leave Me). We spend a lot of time with my Dad without her growing up, I have a lot of great memories of hiking/backpacking/camping with him and we're still close. His is close with all of us kids, weirdly.
