We are in a group of women, 8-12 depending and have regular meet ups (dinners) once a month at rotaing houses.. New person joined she doesn't work but is ok financially. She is hosting next and sent the date. We have all accepted. She said "no need to bring anythign just bring your selves" type thing.. and I replied no no we always pitch in and contribute for each other.. starters, a main plate or desert and contribute to the alcohol and one of us (usally all) pitch and help clean etc aftetrwards, so as to not leave too much for the host to do the next day.. its been like this for three years. I get a message afterward "why did i pitch in and say tall that i should have left her to it" (to provide everything!)_ by another member of the group.. is this a CF or should I have not said anythign.. ?
