Hello, monkeypaw7 &

I am truly sorry for the problems you are having, and I do know how hard it can be trying to understand and deal with a loved one with BPD. You are not alone anymore, monkeypaw7... .We are here for you
How old are your other children? How does your wife get along with all of them? I do know how difficult and frustrating and painful the Jeckyl and Hyde behavior can be, and something I think that will help you understand it better is if you check out the
links to the right-hand side of this page. It's great that you have read "Stop Walking on Eggshells", and all of the information on this site is really very helpful in giving more information on how our BPD loved one's mind works, and what we can do to help make things better.
Again, I'd like to encourage you to check out all of the
links to the right-hand side of this page, and this also would be helpful:
When a partner, spouse or girlfriend has Borderline Personality Disorder. There are several Feature Articles there with information that will enlighten you and give you food for thought... .I really encourage you to take the time to check out the information here, continue to tell us your story, and ask your questions. We're happy to help, monkeypaw7
