>>31138709This happened to me when I was younger. We'd get into an argument about something stupid, she'd get mad and disappear. Inevitably she'd come back and act like nothing happened. In the end I got sick of, realized it was manipulative and not healthy for either of us, so the next time she tried to come back I told her to fuck off.
To be honest there was a lot of other stuff going on between us too, but this is the short version It sucks at first, but in the end it's better. Having a friend like that is really stressful and it's not worth it going through all the suffering just for them to toy with you like that.
