NLT, You have a good attitude about your situation. Yes, mlc is a long haul, but if you can reconcile at some point, it will be worth every tear, frustration and chaos that has come about from h is crisis. I know a few who have reconciled and they have told me that they are happier now than they were before because they both have changed for the better. Now, that's something to look forward to.
Yes, your h is speaking the mlc lingo. They have this fear of dying and sometimes it's because they see their friends, co-workers and parents passing away and/or aging right before their eyes (us too), and they don't want to get old and have health issues that go along w/gettng older. So, they deny it and run like heck to the hills, but they don't stop to realize that no matter what they do, they are still aging and their bodies can't continue to go 24/7 like they may have when they were in their teens and/or early 20's. But, it will catch up w/them at some point.
I'm glad he phoned to tell you he had enjoyed the evening. At least he recognized you for looking nice. There's no need to call him back unless you want to.
As for the parking situation, I think it's an old habit and also it's his way of keeping one foot at his "old" home and one at the other. It's a way to observe what is going on at your home and not wanting to cut all ties. They have to have a life line to the old life during mlc. It's strange, but they need that one little string from the past to keep in their pocket, very similiar to Alice in Wonderland, if you ask me.
NLT, don't doubt yourself. You are on the right track. Continue as you have been doing. He feels comfortable around you and that's important.
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.
