bestie blocked me for 3 weeks & still counting

hey everyone, hope all is well <3

to make this story short, my bestie blocked me on everything (number and snap) cuz i wasn’t there when she needed me on our camping trip. i didn’t feel like getting up and leaving the tent to FT her, (which she requested) so i told her i’ll text her instead and then she said “whatever girl” and hung up

so that’s when i became blocked (sept. 7) and she stopped sharing her location w/ me and i couldn’t find her on snap anymore.

i had my boyfriend call her and she told him that she really needed me and was upset that i didn’t want to leave the tent. my bf told me “babe, you gotta be the for the ppl who are there for you” and i feel so bad now. in HS our petty fights would last like a week.

now i know i fucked up and i acknowledge that, i should have just left the tent to talk to her. when i told my bf she blocked me, he was like “wow it wasn’t that serious”

side note: this camping trip was planned by both of them cuz they know my mom is controlling and won’t let me leave the house so when it came close to the day, she wasn’t really that responsive to our group chat or calls. it made me feel like “you don’t wanna see me after not being able to since before quarantine?”

the day before she told me she wasn’t able to get work off cuz it was labor day weekend there was no one to cover her. we had been told her to take care of that a few weeks before the trip.

then the day of she text me and says she won’t be able to come on the trip cuz her mental isn’t right and had plans w/ someone else ..... (i’ll post pic below)

one more thing: when my bf and bestie went hiking a few weeks before the trip, he told me that the way she would talk about me i came up was kinda fake. he said she seems like the type of friend that would throw me under the bus to save her own ass.

now maybe i’m oblivious to that but he’s very highly aware of others and energies and i’m not so i actually do believe him.

of course that doesn’t negate the fact that i was a shitty friend when she needed me. and now i’m blocked and don’t know what to do ? my bf said i should just leave her alone cuz friends come and go but i wanted to apologize but i can’t even contact her now

what should i do ???
