Be harassed by your lover and ask to break up. What should I do if he threatens me?

I want to divide it myself, and the other party can't force anything ~

Ignore and be indifferent, and see how long the other party can persist.

Of course, if you feel that you have lost something, you can ask for compensation appropriately and settle it through consultation.

I'm afraid I don't want to break up. Handle it properly ~

It depends. Calling the police is too much ~ it is illegal to interfere with the normal life of others. This is called harassment.
