After the blind date, he said that he was not reluctant, but he never sent a text message. What should I do?

In that case, he had a crush on you before. You said he was busy recently. He probably likes the type of good girls and thinks you are busy with things other than work. If you really have a fate with him, I believe he will know the truth about you and will continue to chase you, but it is best not to explain yourself. This will make him think that you are chasing him, and he will be bored. If you don't have a chance with him, you'll have to go on a blind date.
