Seriously, I don't know about your state, but unless you are abusive or have a very severe drug/alcohol problem, and have been in trouble with the law, it would be very VERY difficult for your wife to take complete custody away from you.
Just ignore the whole thing. Your W is living in some fantasy right now and she is also presenting you in a negative light to MIL. The entire thing is completely out of porportion. The best thing to do is stay out of it. Ignore it. Don't try to defend yourself or you'll only fall in it.
(BTW, it never hurts to have a list of great lawyers hidden away... like in a drawer at work... hopefully you'd never have to use them, but at least you'll feel prepared if you ever do...).
There is no arriving, ever. It is all a continual becoming.
