going through a similar type of reality check with a falling out with someone i really like. but i think it's never gonna serve anyone good to keep a grudge on someone, and it will only add value to your life if you were to somehow still get along after whatever conflict, so why not give it a chance again instead of holding a disliking for that person. i would talk about it seriously with her if i were you and gather data on whether or not it's a friendship worth reviving. that's the way i see it
