I broke up with my boyfriend, but he threatened to come to my school and ruin my reputation. He will kill himself.

You'd better be careful and take precautions. We can't admit that he is harassing us.

In fact, since we have broken up, don't contact him. It's clean and can't be delayed, so he feels there is hope of recovery and can continue to play with you.

But you should also pay attention to preparing a successful candidate. If you really can't, you really call the police. Before he jumps over the wall and does something drastic to you.

Generally, hypocritical people like this are soft-hearted, afraid of hardness and lip-synching. As you said, this person is very likely to commit a crime, so you should be careful.

Whether you go out, cross the street or go anywhere, you should pay attention to the surrounding situation. Remember to lock the door when you sleep at night, and you'd better change it.

Even at school, we should pay attention to not being alone and being with everyone.

No matter where you go, stay with a few people and try not to be alone.

But don't be afraid, don't be afraid every day, as usual. Have a normal mind every day. Don't let that person see that you are afraid. Maybe he will follow you. As long as you don't know anything, call everyone in the same class, preferably more than two. Because if he does anything drastic, there are people around you who can help.

The last sentence, be careful, keep a normal heart, don't be alone, and be ready to call the police at any time to prevent that person from making excessive behavior.

Bless you!
