@Xzayer You see last year me and a couple of my close classmates were working on a project and a dude was in charge of having a diary that had all the plans and things written in it. One random ass day he came to me and said ,"I don't wanna get involved anymore heres your diary bye". I was just like ok cool. Then the next day he came to me and said, "I thought yall needed me ,why didn't you beg me to stay?" I was so flabbergasted that i didnt know what to respond with. So yeah ,high schoolers do these things.
I know its not the same as a breakup but I thought it had a hint of the same behavior so that's why i commented.
