Oh I still am soooo appreciative that OW's H contacted me and felt I needed to know what he knew. My own H couldn't tell me the truth, and being in the dark was horrible. Just awful.
Before I knew he knew, I debated hourly whether to call him. But he already knew.
And yes, I wonder (even though H says NO ONE knows) who thinks of me as a fool as well. I am sure people at H's favorite bar (where he basically dated OW every weekend) wonder quite a bit. I bet they thought SHE was his wife.
