I used to work for an attorney who practiced family law. We had one client who was in the military ... tall ... in shape. His wife beat him. I don't know how long he had withstood her physical assaults on him but he finally decided it was better for him to get a divorce from her because he was afraid that one time he would respond by hitting her back. I guess he finally had enough.That approach is unusual. Many police officers are trained in the "Duluth Model" which teaches that women are never the abusers. The injustice resulting from that is profound.
Tough, too, because they had kids. Sad for kids to be in situations like that ...
