Thanks a lot for the responses folks. You're really helping me with this. I want to do everything possible so that my kids get thru it all okay. One problem is that W is in denial about it and is convinced that this split is a great positive thing and so why would anybody need counseling or therapy or feel bad about it. So she resists my efforts to arrange counseling with the kids.

I'm also convinced that her new relationship will be problematic and that she will continue to slip into this MLC-type confusion that has engulfed her. It sux that the kids need to be embroiled in all of that. My plan is to make things as simple, familiar and relaxed for the kids as I can during my 50% of the time with them. Ultimately, I suppose that's all I can do.
