Dar, When H and I were S, he wanted nothing to do with me at all. I felt the same way you do...maybe its not MLC maybe he just wants out.
We know that men and women do not think the same way emotionally. We tend to read into everything, men don't. The fact that your H doesn't intiate contact doesn't really mean all that much.
When H did not contact me, I did not contact him. It came to the point that he didn't know anything going on with the kids because he never called to check on them and I finally decided if he wanted to know badly enough he would call...otherwise that I was not going to be his secretary!
H and I have reconciled...so the "maybe he's done..." isn't necessarily true. I felt the same way and I was wrong~!
