One more note on my hopes for another chance with Mr. A and what seems different now:

There have been a bunch of times since Mr. A left when I thought we might have chance to turn things around. Sometimes I made blatant bad judgments, like the time I hadn't seen him for over a month and then we finally got together and I put mucho pressure on him to move back in immediately. Obviously that did not happen! Or the time I sent him an email that just contained this link:

Or many, many other examples of foolish behavior.

But then there were times that I conducted myself with a lot of dignity, and Mr. A still didn't want to try to reconnect.

This time he seems not only to be open to reconnecting, but to be actively pursuing a reconnection with me. So that is a 180 for Mr. A!

Sorry this is kind of disjointed but I'm posting at work - interruptions galore!
