Thank you, all of you, for your thoughtful advice and encouragement. I truly appreciate it.
I have one question, though, that hasn't really been answered: Does anyone see a way for me to undo the damage I did by effectively slamming and barring the door on H when I told him we would not be friends?
Being somewhat familiar with this new version of H, he's going to show up Monday in a foul mood and will take every opportunity to be ugly to me. He usually does this until I apologize. I don't intend to do so this time, but I'm interested in how to let him know that when he wakes up, I'll be happy to talk to him - but until then, no.
Has anyone gone through something similar, and if so, how to repair?
