Group of friends from school and we've all got along. But one Friend has always been a bit flakey and a bit childish. Started going out with a guy about four years ago who was bad news, got her into lots of debt and generally just awful. Anyway she's the sort that can pick you up and ditch you when a new man comes along or new friends etc and since him she's got worse. Apparently her DP thinks we're all rubbish friends to her and she was telling me this last year.
In the last few years she's not bothered ever coming to things, says she has no money, never makes any effort to meet up but then is always on FB going on holiday to the US, buying new car etc.
The others have got fed up and drifted from her. I made quite a bit of effort to stay in touch until last year where for the nth time she cancelled on me an hour before meeting up and since then I haven't bothered much either - cue lots of messages suddenly asking why I've cut her out when she sees we've met up without her. I've explained I haven't and she needs to make an effort and that also Im not responsible for things others organise and she needs to be more proactive with the rest of them but not much has changed.
I haven't heard or seen her in a few months and today I get this message "why did you bother convincing me you weren't trying to cut me out of your life?"
It's really pissed me off. AIBU not to reply and just block and if IABU what should I say instead? I don't want this to escalate. Her DP is a pretty nasty character and last time they fell out with a friend they reported them for working cash in hand whilst claiming JSA.
