Well, here's another follow-up, if anyone's still listening.
As I said, when he called Tuesday night, he suddenly had to get off the phone when I starting saying anything about myself - i.e., telling him I had been sick.
When he called last night (only one call yesterday), he told me all about his adventures on vacation and was ready to hang up. I started telling him, doing his parts and my parts of the conversation, about my day - e.g., "Well, my day was good too, thanks for asking. I was busy at work but I'm feeling better..." This admittedly was a sarcastic approach, which wasn't the best idea, but I had been aware of the one-directional supply thing happening again. His response was "Well, if your goal was to make me feel bad, you succeeded." I told him that no, my goal was to say something about myself. He actually made me feel bad for him that he had been inconsiderate!
Suffice it to say that things went very badly tonight, as he was still holding a grudge because I had criticised him last night.
I know there's no particular point in sharing all this, except that I know someone out there understands how maddening these things are, and that helps.
ccumm36D, I wish I could call Father Damien over! Come to think of it - I'm the one who needs the exorcism to get him out of my head!
