People move on after mistreating you. They're not sitting up in a room crying and thinking about you. Most of the time they move on and live perfectly fine after doing you dirty. So release yourself from the shackles of waiting for someone to regret how they mistreated you.
Go live your best life.
It’s really selfish to enter someone’s life, see that they’re a loving, cheerful and good person and decide to ruin their peace because you haven’t dealt with your own issues.
