A boy who likes me sends me text messages every day. How can I gently tell him not to send it again? _?

Ignore him. If you pay attention to him and tell him that you don't want to send anything, he will think like this: Hey, she noticed me, but she wouldn't let me send it because she likes me. Girls are shy and have to express themselves euphemistically. Therefore, the best way is to ignore him. If it's from him, you can ignore it. If he asks you in person why you didn't reply, you should say that you didn't see it (a self-respecting boy will understand the meaning of this sentence unless he is a diaosi).
