Viki, I re-read your post and don't doubt for a second that your EX-Husband is still stuck in the tunnel; it reminds me of a friend of mine, whose husband went on and married the other woman....he was and still is stuck in the tunnel, but trying to move forward, and I can tell you, she's GLAD he did what he did. She didn't need him in the shape he was in...and when she realized that; it threw all the "what if" questions right out of the window...and she gained her freedom. It took her a couple of years to realize that as a fact. She is now remarried, having gotten something better than she had before.
Remember, as each person is different, every MLC/Transition is different..what works for one may not work for another. Most of the time it is trial and error for ALL involved.
