Would you reveal your heart to someone you never got a chance to?

Imagine there was someone you liked. You guys just couldn’t be together… In the end, you pushed him/her away because nothing was happening. He/she was either intimitaded or scared that you are different. But he/she liked you some time during the year. Now, you won’t see her/him as often. Would you reveal your heart even if their feelings have changed? Would you keep it forever? How would you reveal it?
