I say good night to my favorite gay man every day. I sent him a message last night, but he didn't reply. Can you explain that he turned me down?

Can't say that the other party rejected you? After all, you didn't confess. If you confess, he refuses you, which means he doesn't like you. In fact, did you miss whether the other person has a girlfriend? What kind of person does the other person like? If you send him good night every day and the other person doesn't feel anything for you, then he really doesn't want to talk to you. I think if you find out what type and personality the other person likes and do what he likes, you will get twice the result with half the effort. For someone you don't like, you send her good morning and good night every day. If there is no nutrition, the other person will definitely feel bored. It can only show that your male colleague certainly has no feelings for you, and it can't show that she rejected you, because you didn't express your feelings to her, so there is nothing to refuse.
