Anonymous wrote:OP, you are being ridiculous. You SAH. (I do as well) You have plenty of time. It's not that hard to clean the house and host a family party for a 70 year old. Why on earth would you want to hurt your MIL and cause family drama? Being part of a family means sometimes putting others before yourself. Host the party, then reward yourself with a yoga retreat the next week.
This is some sexist bs right here. I'm another sah with ils who expected me to host and party plan for their inconsiderate family. Op refuse to house anyone other than your mil and fil. The other adults need to get a hotel. Take a hard line on that one. You are stuck hosting this year but do less. You are a sucker who let this go on too long. You are not obligated to be responsible for anyone else's celebration. My ils were takers and I was the sah who they tried to take advantage of. Start saying no.
