Mike once again Janine is right. Focus on the boys. They are the most important and seem to have been focused out by your WAS. That should make you upset but do not show her that. It is important that you keep things as conflict free as you can. It is important, as stated before, to not use your kids as weapons. They have their own voices so let them tell her if they want how they feel.
As MLC stated, try to keep the lawyer talk to a minimium. That is very hard for me right now as we seem to be in that stage as well. But try. Stay positive and avoid as much conflict as possible. The lawyers will take this into account if things end up getting nasty.
Also, the drug abuse is a serious thought. MLC is spot on again. Drugs can help much, but that are real easy to abuse. She sounds like she is trying to completel 'forget' aboutthe whole family. As I had stated, my son had surgery, I don't see how a parent could forget. AT ALL! That is just rediculous. Keep and eye on that.
Good luck to you buddy. I have been thinking about you. Keep your chin up man. Do what you have to do to take the high road. I know that sometimes it is the hardest route to take, but you will be happy later that you took that route.
