A man, my best friend’s boyfriend

I personally think your best friend should break up with her boyfriend immediately. Being too late can be life-threatening. There are two possibilities for his behavior. The first is that he does so much just to hope that your best friend will pay attention to him and care more about him, so he behaves like this. The second is that your best friend’s boyfriend is very mentally ill. He may have mania and persecution delusions. These are serious mental problems. You should seek medical attention as soon as possible.

In today's society, everyone is under great pressure, especially men. When I feel stressed and have no way to vent my anger, I often lose my temper and break things to vent my temper. But if your best friend's boyfriend feels like he's letting off steam, there must be a serious problem. Don't be careless about this kind of thing, otherwise the consequences will be serious. Either leave as soon as possible, or send him to the hospital for examination immediately, as he is afraid of serious consequences if it is too late.
