I've been part of a group of six since going to uni together, still all live in the same city. As life has moved on over the past 10 years I just don't feel we have much in common any more. Meet ups are infrequent and, to be honest, I don't want to give up my limited free time to spend a £60 on wine and dinner. I allocate £10 a week as disposable income so I have to dip into savings to cover it.
I've just started politely declining, but it has been noted as there was a rash of meetups over the summer holiday. AIBU to continue politely saying no thanks? I don't actually dislike them or bear them any ill-feeling so officially breaking up with them seems a bit over the top!
