I'm part of a group of 5 friends who regularly socialise together. One of this group (Sue) i've always been closer to than the others and we often meet up as a pair. The other 3 friends i only see as part of the group of 5.
Over the past 6 months Sue has done a number of things which have started to erode our friendship (being critical of me, tellling me white lies, being unsupportive when I was going through a difficult time etc). Each time I've been annoyed but have seen it as a one off incident and quicky forgiven her. I also haven't said anything to the rest of the group.
Today I confronted Sue about a lie she'd told me last week and realised that the number of 'one-off' incidents is so high that I no longer trust her, or feel supported by her, or want to spend any time with her. The problem is, avoiding Sue means also avoiding the 3 other friends. I don't want to draw them into our disagreement, and don't want to bad mouth Sue or ask the other friends to take sides. Has anyone advice on how to continue spending time with a group of friends when you actively dislike one of the group?
