why do my friends leave me out?

[Nicole]

Well it seems like they haven't hung out with you in a while... So they probably forgot how fun it is to hang out with you. I wouldn't cancel the sleepover. Just make sure to make it super fun so they will remember how much they love hanging out with you.
But... If they leave you out, that doesn't make them good friends at all. If they keep it up after your sleepover, find new friends! They're not worth your time. And when they said "I thought you went shopping". no. That's not why they left you out. That's their excuse.
But I don't know. Try what you think would work. If nothing helps eventually, then they're not good enough for you!
I hope your situation gets better, love! xx
