When I was going through my divorce, another guy I know got slapped with the traditional restraining order.
Seems he'd found out his wife was unfaithful, but confronted her before he had evidence. She called the police and proceeded to trash the house, rip her clothes, and as she saw the squad car pull in, attacked him.
Who did the police believe? One guess.
He lost the house, the car, the kids, paid 1800/month in child support (in a much lower geared economy than folks on the coasts are used to, in 1990) and even had his firearms taken away--with the right to own one under Clinton.
One little VHS videotape saved me that.
Unfortunately, guys who get custody of their children are still few and far between.
The wife in the case I cited is a Methamphetamine addict (the case where the guy got custody of his kids), so the judge didn't have a lot of choice, except to farm the children out to foster homes.
Don't let the exceptions cited blind you to the overwhelming majority of cases which go the other way.
