DEAR ABBY: Our daughter-in-law is morally corrupt, egotistical and narcissistic. For almost a year she has been blatant about having an affair and has abused and disrespected our son and two of her three daughters. She has taken innumerable vacations over the years without our son. When they are together at home, she constantly puts him down and psychologically abuses him, usually in front of his younger daughters.
She tries to meet her boyfriend whenever possible. Usually, she sends him a text and then goes "shopping." If my son is around to watch the kids, she'll just leave. If she's home, she has long phone conversations with the boyfriend, even though the children are present.
The oldest daughter knows what's happening, as she has told her dad as much. The funny thing is, his wife thinks no one knows what's going on when we all know what's going on. All we can do is encourage our son to get a lawyer. That's probably just what she wants, so she can make him the bad guy. Thanks for any suggestion you might have. -- MYSTIFIED IN MINNESOTA
