Thanks all - - it's good to get some perspective since mine has left me for the time being.

I'm not annoyed that he took the time he did to respond, it's more that he didn't check that I was OK and just sent a 'hope everything is fine' message without followup. That's my fault for not including context, but also his because his boundaries are so flipping rigid I didn't feel like I could text him the context.

Will talk to him tomorrow. Hopefully he'll admit some fault or regret, instead of his usual 'I'm sorry you feel that way'. I'm not holding out much hope though.
