I would start calling him out on his comments, "What would make you say such a horrible thing to your wife?" Or laugh and say, "When you say comments like that, it's no wonder you don't have many friends"
Certainly agree with what you say . Why is it always women that are submissive , gently quiet no matter what’s said to them , men don’t put up with any nonsense as a general rule.
As regards to this obnoxious man , think it’s best to create a distance from him , just be slow in responding to messages and say you’re too busy or something. As regards to his wife , I personally wouldn’t want to make a friend out of her mainly because the type of woman she is , bit of a doormat .
