i fucked my best friends ex someone help

my best friend dated this guy carter for a while and their breakup was pretty ugly. i was snapping him, giving him shit for breaking her heart and he told me to come over so we could talk about it in person. he lives only a block away so i snuck out and went to his house. i swear i didn’t mean to. he just grabbed me and i didn’t stop him. so i wake up the next morning and i didn’t know what to do so i faked sick. it was a thursday the night it happened and i skipped school on friday so i didn’t have to see either of them. i’ve been avoided both their snaps and calls and texts but i have to see them both tomorrow i don’t know what to do someone help please.
