I agree: take a breather and GAL. Glad to know you have a full plate ahead.
I can also sense a shift in YOU, mdu. I think you're at the place where you CAN step back a little and detach. In fact, it seems you're already doing that. You've come a long way.
Remain warm when you see him ... but act a little mysterious, too. Keep conversations short. You end them first. Dress nice, wear the perfume he likes. You know the drill. Make him wonder what YOU are up to ... all while remaining warm and neighborly with him.
If I discover for sure that he is involved with her again Are you planning to try to find out?
