My ex-boyfriend always hurts me and hits me. What kind of psychology is it?

Ex-boyfriends always hurt you, probably because they have some negative feelings about you, which may include dissatisfaction, disgust, jealousy, inferiority and so on. Specifically, the following are some possible psychological reasons:

1. Jealousy: An ex-boyfriend may try to hurt you because he is jealous of some aspects of you, such as your appearance, talent and achievements. This jealousy may be because he thinks you are better than him in some ways, so he tries to find his sense of balance by belittling you.

2. Inferiority: The ex-boyfriend may feel inferior because of his lack of self-confidence, thus trying to raise his position by hitting you. This inferiority complex may be because he thinks he can't succeed, so he tries to find his sense of existence by belittling you.

3. Dissatisfaction: An ex-boyfriend may try to attack you because he has some dissatisfaction with you, such as your behavior and hobbies. This dissatisfaction may be because he feels that some of your behaviors make him uncomfortable, so he tries to make you change by belittling you.

4. Dislike: The ex-boyfriend may try to attack you because he has some dislike for you, such as your personality and values. This disgust may be because he thinks some aspects of you disgust him and tries to make you change by belittling you.

No matter why your ex-boyfriend hit you, it is not recommended to continue to associate with him. His behavior may have a negative impact on you, making you feel insecure and depressed. If you are troubled by your ex-boyfriend's behavior, it is recommended to communicate with him or seek psychological counseling.
