Selective amnesia, still able to continue on with his career and the rest of his life?...
I wouldn't buy it. Now, if I wanted to, I'd insist on testing go to the doctor with him and keep a private investigator looking into a possible double life, and an attorney. The attorney, dr. and pi would enable her to better act in the future to protect her family.
A double life or extreme disregard for his wife and family, that makes sense. His actions and behavior just don't make sense or sound like amnesia. She really needs to look into preparing for another blow-up and walk out.
She sure has a lot on her plate.:grouphug:
