Dad had an affair, and when the stepmother found out, she broke off the relationship with the third party, but the third party sent us threatening text messages. What should we do now?

Owner, I have a similar experience to you. But I was still young at the time, and I didn’t know how to tell my dad, so I just scolded the guy and told her to get lost.

It would be better for you to discuss this kind of matter with your father and the other adults first, to find out what that guy wants to do.

If she keeps harassing you like this, just call the police!

If calling the police doesn't work, get a few people to go to her house and scare her. If she is really mean and panicked, you might want to beat her up. At most, the medical expenses will be paid afterwards. Some people are like this, and they have to be beaten before they realize their mistake. However, this method is too extreme, so you might as well call the police = = I hope it will be helpful to you.
