I Have BPD - Borderline Personality Disorder

I love someone who is excessively moody. Being around him is like tiptoeing on a minefield. I've consulted Dr. Google and I seriously wonder if he has BPD, but he gets upset when I bring it up. Maybe he is just ultra-sensitive?

He is not always this way, but when it comes out I have serious doubts about my future with him. Being on constant guard with a person is no way to live.
