You may miss an opportunity to allow him to see the person who is becoming newer, better, more attractive.

If your fell YOU could not resist, than don't meet with him. It would take huge risk, courage, strength to meet with him and...

just be friends...

Again, please remember that the two of you are still M. The "idea" might be that you are the OW... the reality is, SHE is STILL the OW...

It is up to you to decide what you want to do.

I do think that getting together with your H for something casual, but fun might help.
