I confessed to that boy, but he didn't answer me. He just kept chatting with me and said he would pick me up for dinner.

I asked the boy to confess, but he didn't answer you. He has been wanting to chat with you and said that he would have dinner with you. It doesn't prove that he accepted you. Maybe he turned you down at dinner with you.

You have to wait patiently for the other person to see if you really accept yourself. If you confess that he likes you, he will tell you next time and give you a clear hint.

However, there may be some accidents. He didn't answer you, but he told you through his actions that he likes you.

Since he has come to pick you up for dinner, why don't you go out for a while and see if it suits you? If you think both sides are suitable, then you can develop well. If one party feels inappropriate, it is also urgent to break up.

If you like it, you should strive for it so that you won't regret it.
