A good friend of mine who went through a terrible MLC-based divorce (I was a bridesmaid at their wedding) gave me some very good advice, though I haven't truly followed it. It was to see the divorce through as quickly as possible, and then get a guardian ad litem AFTER the divorce. Pay that person yourself and have that person inserted into your lives, advocating for the kids through all the visitation stuff, keeping records, seeing what is best for the kids. I think with a crazy MLC-er, custody issues will keep coming up, and it sounds like you may need to protect your kids from some crazy stuff before your W comes out of it. I didn't have to do 50-50 but if my H ever tries that down the road, I will go for the guardian.
I believe I will see the bounty of the Lord in the land of the living. Wait for the Lord with courage. Be stouthearted, and wait for the Lord.
