I've read this entire thread and it seems to me that you keep asking what you should do and when people give you advice you don't like you dismiss it. Look, this woman cost you your job, she obviously physically assaulted you, she is no where to be found and hasn't bothered to contact you. None of that sounds like love to me. You need to get your life back together. Go get a new job, maybe meet a woman you don't have to take care of constantly. Your first wife died of cancer and you said you took care of her the entire time. Now this wife is bi-polar and you are contantly taking care of her. Take care of yourself for once.
I also get the impression that you are an enabler and actually like the drama so telling you to move on will fall on deaf ears.
Seriously, move on.
