I don't post too terribly often but I came across this thread and thought I could share.
My H did the exact same things. Many times he wouldn't look in my direction at all. One time he dropped our son off at the end of the driveway, and then took off. This happened off and on for more than a year. Last summer he was so angry every time that I saw him, he wouldn't look at me, he never got out of his truck. I just kept being pleasant with him.
I don't know why they do this but I think a big part is because we are doing okay and moving on with our lives and they are still stuck in the dark abyss that is their life.
It is interesting to see this in these MLCers. My older sister is doing the same stuff. Only her H after the divorce stays away from her so she is taking it out on our family instead. She is really angry with all of us and we really don't know what we did.
I always tell myself that he is just projecting which as painful as it is it also is like a window into his mind to let me know where he really is emotionally.
I hope that this helps. ST
