Urgent ... what should I do if I meet a mental derangement?

Hello, my friend! First, I sympathize with your misfortune. .

Careless friends can only blame themselves for their bad luck. Remember this lesson and you won't make the same mistake again, will you? Learn from your mistakes.

There are all kinds of people in society, and of course there are such people as you said. These people are mentally unsound, that is, they have mental illness. Don't pay too much attention to him, he will push his luck. He is the kind of person who won't stop until he gets what he wants. I think the only way is to turn a blind eye, listen without hearing, and do what he should do. Don't delay his normal life, let time wear away his patience. Maybe one day he will suddenly lose interest in you and disappear naturally.

Cut off contact with him at ordinary times and don't give him a chance to contact you.

Have a happy day! We are not angry, and we are not as knowledgeable as psychopaths. Hmm. How interesting
