With such a laundry list of psychiatric disorders, I don't know how anyone could expect "normal" behavior out of him. However, I can't imagine why you insist on clinging to such an unstable foundation. I believe most people would be running for the hills. Seriously, I believe you would benefit from some intensive therapy.
And no, I don't think you should consider your level of commitment to this man to be some sort of badge of honor, in case you were thinking it would reflect well on your character. It is never a good thing when people cast aside common sense and their own well-being in the name of love and/or commitment.
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
