It sounds a bit like what my WAW is doing to me, trying to connect in different ways. The advice I've gotten here and elsewhere is to ignore it. I simply don't respond. It's a way to make them feel their loss and for us to detach. It's taking her a lot of time to stop, but I think we got there in the last week. She still chatted me last week to offer a book recommendation though. I didn't see it until 3 days later and, again, chose to ignore it. I'm going for the DB Soldier of the Year award.
I understand the desire to reply. But when I resigned myself to stay silent, I feel better and prouder. Also, your email kind of suggests you were done. He might find it later even if he hasn't read it yet. I know I sometimes verify my junk mail folder.
