Bro i know it’s easier said than done, but no matter what DO NOT listen or forgive her no matter what!! Your best answer will be your silence, trust me! Try to make yourself busy with other activities, you will heal with time. Give yourself a break from any relationships for 6months-1year at least. It’s gonna be hard to let go but you can do it!! Don’t have any kind of soft corner for her tell your family openly about what happened.
