If she don't start off with an apology fukk all that.
That's why you bring it to her attention. A lot of people feel that they aren't obligated to apologize because they don't care or don't see what they did wrong. If she still doesn't apologize, then there's no need to feel salty about a thing as you now know you were messing with someone who really dgaf.
Op is obviously invested so its best he finds some closure so he don't harbor resentment for someone like that. She wouldn't be worth it in that case.
