On an earlier thread, it was pointed out that for an ex husband to have custody is rare in Texas. The woman either did something blatantly wrong or took great pains to forsake the children. The whole charge might be a lie.
Reread the article. It says they share custody, which is pretty common.
I hope the woman goes to family court to get 100% custody. There must be *something* she can pull out of the closet to get her girls away from that man.
