Should I text my rival so that she won't bother my husband? (Texting politely)

Never mind, you can send this message. However, the crux of the problem has not been solved, that is, you have been married for so long. Should we communicate with his mother? Otherwise, today is this woman, and tomorrow there will be another woman. This woman is not in your heart, is it? But the other woman is your mother-in-law. You have to talk to her, or you will really marry your boyfriend and stay with your mother-in-law.
