MacNut, I was meeting all his ENs.

Yep, that's the $60,000 question. How did I start an A when it went against everything I believed in? Circumstances. I've been over this quite a few times here (lol I've got 8000 posts) but it was at a time when our marriage had become difficult for the first time in 28 years (my H was suffering from severe depression from grief - losing his parents and my father all in one year). Enter old HS boyfriend completely out of the blue. That's it in a nutshell really.
