Unfortunately, allegations of sexual abuse are big business. Expert witnesses all around. Financially destroyed families and wary kids who've been mind gamed to death. Usually a bitter spouse who has not let go of an ugly divorce. They exist on both genders. Some spouses are not satisfied with moving on. They want to inflict maximum collateral damage, thinking it will get the "enemy".
Couples with children should not be allowed to divorce, period.
I know, I have seen it around. With her, she was glad he was taking the kids for a while, her oldest is special needs. She loved that she had a few hours to herself twice a week. I can tell you this woman isn't out to get him.
