Apparently Larry David is ok with breaking up a marriage. His current girlfriend was still living with and married to her husband when she started dating Larry David. It was only after they had been dating a month or so that she told her husband, packed up her stuff and moved out. I don't know if she took her daughter with her or left her with her husband. That was an a-hole thing to do by Larry. As soon as Amy Landecker told him she was married he should have backed off. He didn't. Yes, Amy is to blame too, but would you ever want to be known as a home wrecker.
