B4, I know you want to be nice about all this, but considering the mental state of you W I still think it would be better to abandon the whole collaborative thing and sue for custody of the kids. She's working now, make her pay support even if its minimal. In the end it will be better for your kids and and you know it. You have an awful lot of ammunition now and with the way the collaborative process is working you will likely even get off cheaper.
Ask yourself honestly...are you going to get any better deal for you or your kids through the collaborative process? I think the true answer is no, she will never agree to anything that looks like and advantage to you. She is too sick, but you have to see that yourself.
Stand up for what is right, even if you are standing alone.
