(rant below)

so she asked me to come over to her house, i said that i couldnt because i was going to another friends house

she said okay so come over at 5

i said okay and asked my mom if i could go over to my mom's at 5 the next day (because we were having a sleepover)

i had thought i told my friend that we were having a sleepover but i guess i forgot to tell her

i said i could go over to her house because my mom said it was okay

then she texts my other friend later because i didnt have my phone at the time "are you still coming over"

i said "no i thought i told you that i was having a sleepover at my friends house" and she said "no you never told me that"

and then she texts me later and tells me im being rude because i accidentally forgot to tell her that i was having a sleepover at my friends house and that "this happens every single time we want to hang out" even though it doesnt and we literally just had two sleepovers in a row

and then i said im sorry because i legit was and she just says "leave me alone" and blocks me

im really upset ;-;

ive been friends with her since 6th grade and she blocked me over a misunderstanding what can i do
