The boy didn't reply to the girl's confession message.

There are roughly two possibilities: 1: entanglement 2: cold reception.

In fact, did you analyze it before confession? To yourself, to each other. Basic information, personality, likes and dislikes, relationships, contacts, emotional experiences and so on. Need to evaluate before pursuing. Are you suitable? Does it match? Have you judged what kind of boy you are in her eyes? Feelings must be sincere, but they are not rash.

I would rather admit my refusal than have a secret crush all the time. I support it if you like. Another way is to express your confession by SMS, which may require very mature conditions. For example, you know that it is very unlikely that she will refuse you, or you just want to break the window between you.

If this is not the case, it is not recommended to express your confession by SMS. If you are limited by your own conditions, you must try your best to change your shortcomings and really improve yourself, and then choose a suitable way to express yourself in front of her (don't do anything stupid like putting a candle in your heart, which will ruin the streets), and pay attention to her eyes, expressions, tone and movements. And basically judge whether there is a play. At present, I suggest you find a chance to meet her and analyze what the situation is.

If you really like her, give yourself a deadline to let her know that you are good, instead of giving up after being rejected once. If no matter how hard you try, she just doesn't like you, please give up. Don't let good feelings become two people's troubles, or even make others feel harassed. Fate is really wonderful, sometimes you can't believe it.

The most important thing is to make yourself better. Excellent people are not afraid of no one likes them. Come on!
