What should I do if I always receive abusive text messages from a third party (mistress)

Don't warn mistress, flies don't stare at seamless eggs. The important thing is to find a way to find your husband's heart. It's certainly not easy to provoke a man who can be a mistress. You warn her, and she makes fun of you for not taking care of your husband. Don't turn off your phone, just hack her number, or delete the message she sent without looking at the content. Anyway, she won't bother you all the time. I think what you should worry about now is not the spam she sent, but what happened between you and your husband.
