Saw all ILs including extended family 2 weeks before Christmas, PIL, SIL, BIL and their partners etc Christmas Eve, PIL came to us Christmas Day and have seen BIL and partner since Christmas. MIL wants everyone to go to theirs on Sunday so she can have the chance to cook a Christmas dinner. Dh is working and I had made vague plans to see a friend after ds had been to rugby training in the morning. I don't want to go but mil is now being stroppy. AIBU?
