You removed them for a reason. Yes, they may keep knocking on the door, but you don’t have to keep opening it. Every time you do, they repeat the same cycle and you stay stuck.
You deserve to be treated with respect. Sure, no one is perfect, but people who hurt your heart too much never give it a chance to heal. It’s finally time to learn to let go of the people and things that don’t make you feel happy, loved and whole. Trust me. I know you more than anyone else. Love, me.
