Im part of a small group of friends, we've known each other since school and meet regularly, for the last few months one friend keeps cancelling on plans so we then rearrange for a new date to suit her, she's cancelled a few times and when we do meet she always drives, so she doesn't drink and leaves early. We all have young kids and work but try to make the time, its more annoying as she does meet up with ones from her work for boozy nights/bottomless brunch etc. just feels disheartening she doesn't really make the effort and its impacting on the rest of the groups meet ups. Should I say something? She would say we're her best friends etc and ive rearranged things to suit her a few times
