Lou, I'm so sorry that he didn't contact you. The contact that you've been having w/him set you up for disappointment. He's still in crisis and per him, working on his issues.
He's got a long way to go and I think he's actually scared to be on his own. I know, it's funny because he's a grown man, but MLCers can be by themselves for very long. So, when he broke up w/the ow, he was already thinking about the two of you working your way back to each other. He needs to be on his own for a while and figure things out. He's looking to you to rescue him. He's got to grow up.
Lou, you are a wonderful person who is an inspiration to many here...please do not allow his behavior to get to you. Yes, it was a disappointment, but it was a reminder that all is not well w/him yet and he's got a ways to go. Dial down your expectations and if you don't hear from him by Wednesday, then make other plans and enjoy yourself. It's his loss.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
