I'm putting this on here on behalf of my sister., we'll call her L. L has been friends with a woman who we'll call A for many years. A is notoriously difficult. Everything has to be how A wants it to be and if it isn't, you are considered to be 'a bad friend'.
The most recent example was when we were out at the pub for a friend's leaving drinks. A came along. L was coming back to ours to stay. When we were ready to leave, A wanted L to stay at the pub for more drinks and to stay at A's house. L didn't want to. A then got threw a hissy fit and stopped talking to L unless it was to send passive aggressive texts about how L has disappointed her. This most recent occasion was the straw that broke the camel's back, so to speak. L usually gives in just to save the aggro that saying no to A causes.
So, after over ten years of this, L has finally had enough and wants out. A wants L to sit down and talk to give her closure. In most situations I would agree that explaining why you're ending a friendship may help to give both parties closure. But with A it's nigh on impossible. I say this from experience when I fell out with A after being unable to attend a birthday do as I had a new baby that I didn't want to leave with a complete stranger. A just can't sit and have a calm chat. Instead it's crying and shouting and name calling, and you can't get a word in edgeways.
So what does L do? I have suggested that L write to her. At least then the closure can be given without the huge drama. But L isn't sure. Any suggestions?
