Honestly this girl has been through so much with me. She's apart of my family now. But recently her and my brother have broken up.. she seemed devastated at first but now she seems fine.. She's respected some boundaries with not trying to trash talk my brother and I respect that..

But recently we've graduated and on grad night she went on what she calls "a slut run"

She's never done something like this

We're both the type of be in a relationship or texting before making out type of girls

I wasn't upset by this because everyone thinks hmm why don't I go crazy after a break up

The reason I was upset was because she kissed the guy I've liked for 2 years

I've been flirting with him in school

They didn't know each other till I introduced them a week before grad

Idk what to do

Should I confront her

Was she even In the wrong

Should I let it go because we're graduated and off to college soon?
