It's hard to forgive someone who gave you so much pain 😊
Let go of all the hurt from the past. Let of the hate, the anger, and the pain. You deserve to be free from all your past baggage and the only way to do that is to fully forgive the people who did you wrong.
The next person who comes to your life deserves a clean slate so leave the past behind and give yourself a chance to find someone who will treat you better and love your harder than before.
