My boyfriend said he would hit me if I failed the exam.

Is your boyfriend your high school classmate or your student? He is a social worker. They have different meanings. If it's a boyfriend and girlfriend who study with classmates, he said that he cares about you and asks you to study hard and get into a school with him. He doesn't want to be separated from you. Of course, he just said that he wouldn't really hit you unless he was really bad-tempered. In the second case, he will care about you as much as your big brother, let you get good grades and have a good job in the future. Otherwise you wouldn't ask. A man often hits his girlfriend. For whatever reason, even if he apologizes afterwards, such a person is not worth your association. Of course, flirting is not like this, because a man can hit you once, whether it is a boyfriend or girlfriend or a husband and wife, and he will hit you again next time. Therefore, men who hit people are absolutely intolerable. It is good to leave early.
