I got angry several times because I suspected my husband was having an affair, and I knelt down and slapped myself. What does this mean?

This situation may indicate that you are angry and disappointed and feel unacceptable to your husband's behavior. This kind of behavior may also be an extreme performance, in order to expect your husband to understand your feelings and change his behavior.

However, this kind of behavior may also bring some negative effects. First of all, self-harm is an unhealthy behavior, which may aggravate your negative emotions and may lead to physical and psychological harm. Secondly, this kind of behavior may make your husband feel embarrassed and at a loss, and may even lead him to be more disgusted and resistant, instead of really understanding your feelings.

If you want to solve problems with your husband, I suggest you take a healthier and more effective way to express your feelings and needs. This includes direct and frank communication, seeking solutions to problems and trying to understand and support each other. If you feel that you can't handle this problem, you can consider seeking the help of professionals, such as marriage counselors or psychologists.
