Friend I wish you the very best but it sounds like it's gonna get ugly. Falsly accusing me of anything especially abandonment would have uncorked the devil in me. I'd have a talk with a lawyer and see about having that cleared up and then.. well if she isn't taking care of the kids very well I'd document it and go for custody. Don't just assume the courts see you as unfit... make 'em prove it.
