My son is already in his third year of high school. When he first entered high school, I said to him, it's normal to like a girl at your age, you have to think why you like her. Maybe it is because she sings better, her character or her studies. You can see her advantages, but others can see that too, so you have to make yourself better, for example, play basketball better, learn better or get into a particularly good university. All these require you to make more effort during the three years. Only then can the girl you like notice you. Now my son is in the third year of high school and I told him again, remember when you find a girlfriend in the future, you should know what you can do and what you can't do. You must have a certain extent. But you must never hurt her, otherwise you will feel sad and guilty in retrospect if you don't live together in the future. It is absolutely forbidden to step on two boats. If you can't go to a further relationship, you can break up, but it is absolutely not allowed to date two girls at the same time. Because you should know, this is not only insulting others but also insulting yourself.
