I’m 17 & I’m going to graduate this year. I told my friends that I’m going to have my graduation party the day after because my graduation is on a Thursday so I figured I’d get it out of the way. One person out of my friends group however said “What if I don’t want to go?” I said why not & she said that she would rather work, but she would most likely not be even scheduled that day, & if so she can ask for the day off. We even work at the same place yet it is a big company so we can easily put someone else in.

I’ve been having problems with this person for a few months since she got a new best friend & doesn’t talk to us anymore, & gives us limited details. Should I still be friends with her?
