Ok this is probably going to be long (have name changed as well as situation possibly recognisable.) I have two old friends, let's call them friend A and friend B. We all go back a fair way, about 15 years and at one point were thick as thieves.
Friend A is quite high maintenance and prone to being a bit controlling and a bit of a Queen Bee. Friend B is very laid back and is flaky as hell about keeping to social arrangements, has form at bailing out of things at the last minute etc (though in fairness has a full on job and a young child but flakiness predates this.)
Friend A and friend B's relationship has been deteriorating slowly over a period of several years but got to a breaking point about a year ago when friend A publicly fell out with friend B's partner at a party and then slagged him off to her afterwards. Friend A has a long history of being negative about her friends' partners and spouses - they are never good enough etc. sometimes she is right but no-one ever takes her seriously anymore on this topic because she basically tars all men with the same brush (she has been single for a long time.)
So essentially I am in friend B's camp on this situation or I was at the time.
Since then friend A has talked repeatedly about wanting to get back in touch with friend B. Friend B has said she is happy to let bygones be bygones etc and is happy to meet up.
Problem is that Friend B has since agreed to three or four attempts to get us all together and then bailed literally at the last minute. It's hard to know whether she is passive aggressively saying she can't be arsed with friend A or whether she is just being a bit rubbish as is her wont.
It usually falls to me (or another mutual friend) to set these things up and I am getting quite hacked off with having to set these things up and deal with the fallout each time when friend B - inevitably - bails. Friend A is visibly hurt each time she is blown out but the penny doesn't seem to drop and she keeps asking me to set something up again.
I want to say to friend b that she should basically make her mind up, either she decides to cut friend A out of her life properly or she makes and sticks to an arrangement and draws a line under the past but it's not fair to keep dangling the promise of a reconciliation and then bailing. Or should I say to friend A that it just isn't going to happen?
