Sam, what could I possibly add that would top the empathy and inight from Sandra????
Not much! But here's a tidbit...when I was a grad student, my mentor, the Prof I T.A.'d for had an affair with one of my fellow students. She was no innocent flower, she pursued him equally.
Thing is she got ME involved as she needed a confidante (I guess). He wanted to leave his lovely wife of umpteen years for her (she was married too), but she stayed with her H and had two kids. My mentor is still with his W, they have lovely grandkids, have parties, etc.
Thing is, as innapropriate as that was, too, it blew over. It's history. I think no less of Dr. J for his MLC, weakness, whatever.
