It can be hard enough for a spouse or parent to sometimes judge manic episodes (or not). A friend of a person with a spouse would have a harder time yet, as well as people on a forum who don't know the husband of a friend.

I will say that it is nice that you seem to care about your friend and her husband. However, if your friend doesn't agree with you about her husband's mental state, there's surely nothing else you can do and it is likely you are wrong.

Yes, BPD is the abbreviation for Borderline Personality Disorder, not Bipolar Disorder. Even some people with Bipolar Disorder misuse the abbreviation, but it often causes confusion.

This is all I will write in this thread as it is not one that generally stays unmoved to elsewhere on the site.
