I haven't seen the boy I used to like for a long time. I dreamed that he was crying in my dream, and then I saw him two days later, but I didn't say hello to him?

The boy you liked before, I haven't seen him for a long time, dreaming that he was crying in your dream shows that there is his shadow in your memory. Since he is married, you should keep your distance, even if you liked him before, otherwise it will cause unnecessary misunderstanding. It is the right choice to meet without saying hello. I wish you happiness in the future.
