no response, but then i think he's on vacation with his OW right now.
The email i sent was this:
"Hi H
Here's wishing you a Happy Father's Day. I always did admire your dedication to doing the right thing by Step-D18.
I just got back from my graduation. Bob showed up and it was great to see him.
Take Care, W"
Bob is a mutual friend of ours who came to the ceremony just to be nice.
And I don't feel bad now for sending the email. The reason I did it is because we have had zero contact for months. Aren't we supposed to get "unstuck"? Or, "shake things up"?
