I confessed to a boy and he didn't reply to me? ! What do you mean?

Little sister, if the boy you profess is self-abased or introverted, then you can open his heart, as long as you keep trying to express your heart to him and let him know your sincerity. Soon he will open his heart to you, because this kind of boy is afraid of giving love, and he is not sure whether you are joking or serious. So, as long as you continue to show him your mind, he will understand one day, because it will take him a long time to accept it, because his thoughts may not be mature enough. Give him some time (within a year at most).

Personally, I think that individual boys of the same age are slower than girls, so they should be patient and don't want to leave regrets.

If you really like him, during this time, you can get to know him slowly and wait for him to figure it out.

During this time, boys may become more and more stupid. What you need is to tell him: I don't like you like this. Let him know that it is wrong to do so.

Then when he is mature and his thoughts can keep up with you, he will accept you.

Finally, there are two possibilities. If you confess to a boy, he won't respond to you or refuse you. It's probably hanging on you, using your mind as a spare tire.
