Dear Queenie,
My sister’s husband cheated on her several years ago, but she found out from some friends who saw him with the other woman. My sister didn’t break up with him over this and since then she has been trying to keep their marriage together, but he doesn’t seem to be sorry for what he did and doesn’t seem to have changed his ways and I just don’t like him anymore.
Queenie, how can I manage to be polite to him when the family all get together on holidays or other special occasions?—Angry sister-in-law
Dear Sister-in-law,
I know this will be difficult for you, but keep reminding yourself how much more difficult it was, and probably still is, for your sister. On occasions when your brother-in-law is present, avoid him as much as possible, and when you cannot do so, try to put your thoughts about his behaviour out of your mind and treat him as politely as you can manage – for your sister’s sake.
