I know it is so hard to see the damage our spouses do to the kids. It is so unfair and selfish, but trust me there will come a day when the reality of his actions really hit him, and it ain't gonna be purdy.
Please understand, I wasn't trying to be a downer at all. Just trying to help you see a little into their crazy ways. It just seems like the more we (the sane ones) try to help or force them (crazy right now) to see reality, the faster the turn away and harder they run.
It is almost impossible for us to try to imagine how their minds of mush work. I guess that was the point I wanted to make. A normal person, yeah that email would hit'em good. With MLC'ers I just don't know. Again I hope he sees the light.
Focus on your son, he needs somebody who is stable, and your it right now. It's not fair, but it is what it is. You can do it!
I'm praying for you, Take care and talk to you soon.
