What if the boyfriend can't control his emotions and hurts himself?

First of all, I totally understand that you may feel confused and painful now. Quarrel and self-harm are unhealthy behaviors, which may cause serious harm to you and your boyfriend.

In this case, I suggest you take the following steps:

Ask for help: If you feel that you can't control your emotions or behaviors, or you are worried about your safety or health, you should ask for help as soon as possible. You can ask your family, friends, doctors or psychological counselors for help.

Seek professional help: If you feel that your emotions or actions have hurt your boyfriend, you should seek professional help as soon as possible. You can consult a counselor or a doctor, who can provide you with more specific suggestions and treatment programs.

Stay calm: In any case, it is very important to stay calm and rational. Try to avoid using violent or radical behavior to respond to each other's emotions or behaviors.

Establish communication: If there are communication barriers between you and your boyfriend, you should try to establish effective communication methods to better understand each other's needs and emotions.

Finally, I want to emphasize again that self-harm and quarreling are unhealthy behaviors, which may cause serious harm to you and your boyfriend. If you need help, please ask for help as soon as possible.
