Two memorable for me.
One friend complete user, money, lifts, dropped you as soon as she got a boyfriend. We fell out and I reached out to her as I was feeling depressed (as was she): she invited me to hers later in the week, to then say she was ill and posted on social media she was out clubbing.
Other one was this year. Horrible weekend away where she sulked like a teenager (no idea why). Tried to meet up with her a couple of times after and got snubbed, She then started messaging saying she missed me but again snubbed my suggestion of meeting up. I gave up. She’s messaged since and I’ve just ignored.
