I was going to lead with a snide comment like "Amber Heard has entered the chat", but here's the thing... A close friend of mine got absolutely fucked over this way.
One day, out of the blue, his wife went psycho. Divorced him, accused him of abusing the kids, coached the kids to say they were abused, the works.
He lost custody, had court battle after court battle, dealt with the most evil, vile shit said about him, none of which was true.
When he attempted the court mandated visitation she would literally attack him and deny visitation. When he recorded her, she broke the video camera.
Then she up and died from a brain tumor.
He goes to court with the medical evidence for her bizarre behavior, and you'd think that would be it, right? Nope. Court tries to give custody of the kids to HER parents, who are of an age that they can't care for teenagers.
So her parents have to travel from 4 states away to testify that there's no evidence to support the accusations, that he should have custody of his kids.
Whole process took 7 or 8 years and he finally got custody just as one of his kids turned 18 and could do what they wanted anyway.
