I'm sorry that you are in the circumstance that caused you to find these boards.
Your post is a bit confusing. Do you suspect your husband suffers from borderline personality disorder or is bi-polar?
To answer your question, it is typical for people with personality disorders to deny that they have a disorder and become emotionally distraught when it is suggested. From what I understand, they do this because admitting that they have a problem is too shameful or painful for them to deal with.
