I have a totally disrespectful son-in-law. Whenever I’m around him, and no one else is there, he does or says whatever he can to purposefully humiliate me. He’s arrogant and knows that he can get away with it because of my love for my daughter and grandchildren. I have wiped him out of my life. I want nothing to do with him, but I know it’s going to interfere with my relationships with my grandchildren in the future. Am I right to stay away from him and totally ignore him?
