Hi HP - glad you're doing ok. I just wanted to add my note of caution to the contact with your previous OW. Handle with care on that one! Particularly if she was the OW you had an A with (if I've understood right). That's going to be like lighting the blue touch paper and standing back.
It's really really tempting to seek solace from an attractive member of the opposite sex. It can make us feel much better and save us from a pile of hard work and introspection. BUT - if you really hope to save your M, I worry for you that this would take you further and further away from that. Is that what you really want?
Just my 0.2 for you...
