Oh gosh.... Sounds like me a few years ago... Friends moaning about everything and anything not appreciating nothing then back stabbing me when I stopped bothering with them. Sadly many are two faced. Get rid of negative friends best choice I ever made!
Yep use to have a friend like that,the only constant friend use to be me and another girl who she went too school with,she went on a night out with other girl and caused a big argument lost that constant friend, So she started trying to boss me,back stab me etc,put up with it for a while untill one day told her too f off,never looked back since,the other friends she has keep changing all the time,no one hangs around for too long,so no there only popular up too a point and seem to have lots of friends bit dont really as the friends change all the Time because none hang around too long.
