I'm sorry you are dealing with this. Borderline Personality Disorder is devastating both the the sufferer and their loved ones. There are several websites that explain what it is and the symptoms. This one is especially good. NIMH · Borderline Personality Disorder
Therapy is highly recommended for this disorder. Cognitive Behavioral Therapy has been very successful. However, it can take years to make progress, just as it took years for the BPD sufferer to think the way they do.
Good luck to you.
