I've been friends with her for over 20 years, and we were best friends at school. Although looking back our friendship was rather like an abusive relationship, with her being the abusive one. She would be all nice and friendly with me, and I'd feel like we were really good friends and then suddenly I'd go into school and she would be ignoring me, whispering about me, and in a bad mood with me.
I'd end up alone for a few weeks, as she was really popular, and then she'd slowly start to be my friend again, be very nice, and then go back to being horrible again. Just a circle of behaviour really.
Fast forward to now; I'm still "friends" with her, probably out of habit more than anything really. I don't see her loads, but it's dawned on me recently that she is still doing the same thing that she did at school.
I saw quite a lot of her in December; we had coffee a couple of times, and went on a night out (all instigated by her). I enjoyed meeting up with her each time, and enjoyed catching up with her. She then sent me a text message on Christmas day wishing me a Happy Christmas.
And since then she has been really off with me again, and I don't know why, as per usual. It usually starts with her ignoring anything I comment on her Facebook and liking comments from everyone else. She also ignores texts. And appears to be very chummy with mutual friends. It's difficult to explain, but she has always done it in such a way so that it's obvious to me that she's ignoring me but not obvious to anyone else. And, well, it just reminds me of being at school. I know that in a month or two she'll be all over me again and want to meet up again.
I am thinking now though that enough is enough, and that I'm not prepared to tolerate her hot and cold behaviour any longer, especially when I've never actually done anything to cause her to behave this way. She is quite a controlling, manipulative person, and would never admit she was wrong.
AIBU to dump her now, ignore any further messages from her and just to let things drift?
