Tip - Start keeping your distance and decide your next move according to their response

A good move here would be to start keeping your distance from that person or people. You don't need them to be happy, life has something for everyone. However, if they reach out to you, and show eagerness to stay close, you might want to give them a chance and come clean about how you feel.

However, if the other person or people show no interest, its a signal for you to move on and forget those people. If they really do care, they will be concerned about you going away, but if they don't, for you it will be good riddance.
