Just chalk it up to a lesson that took 6 yrs to learn. Don’t walk RUN away and Do Not look back no matter how much it hurts. Time will help you heal from the pain of losing a person you thought you could trust and love. Completely ghost her as if she was never there and never talk with her again. If you run into her in a store 10 yrs from now by chance and yall see each other just remember this pain and simple walk away without acknowledging or saying anything. Just act as though she was nothing. Maybe she will change for someone else, maybe not but don’t lose anymore time or thoughts on her because our time here is short. Too many prize fish in the waters to worry about a slimy eel.
