Everyone grows up from childishness. You must realize this before you can grow up.

Your psychological endurance is very poor, and you dare not show yourself. In a word, it is cowardice.

As long as you do one thing well, you can mature yourself a lot at once:

Then express your emotional feelings and respect others' choices and ideas.

The specific method is as follows, as long as you dare to say a few words in front of girls.

First: I want to tell you that I like you,

Remember, just say you like it. You can praise her merits. Don't express your demands and say that you want someone else to be your girlfriend or something. That will only expose your childish nature.

Second: apologize to her sincerely and speak your mind directly. I just like you, so I can't help being jealous when I see you close to others. Now I know this is wrong, and I will try my best to correct it.

As long as you dare to say these words to girls calmly, I promise you will feel much more mature.
