I will be spending Christmas with my DP and DS at my mum's house which is 4 1/2 hours away. After staying at my Mums we will be driving back down the country with my Mum to visit DB and his family. It is a 3 1/2 hr drive from my Mum's house so we will all be staying the night. My Dad will also be staying at DB's house although my Mum and Dad are divorced, they are friends and will both often be present for family meals, birthday parties for the grandchildren. Considering the size of the dinner party that night I offered to bring a dessert for 6 adults, happy to ease the pressure on DB and SIl.
Anyway, they have taken this offer to mean I will do any course and I have now been told that I will be buying and cooking the main meal. I am allowed to use their kitchen or they are happy for me to bring something cooked in my mum's kitchen!
I am feeling resentful over this for a few reasons- we are paying a fortune in petrol to visit them, we have a long journey and I will be 30 weeks pregnant by then and will not really fancy going straight to the kitchen to prep the evening meal after traveling 3 and 1/2 hours. Finally, my DB has a very good job, they are very rich, we are not very well off, is it unreasonble to expect to not pay for the petrol to visit and the main evening meal. The last time we visited DB we paid for a restaurant meal for my nephew's birthday and the petrol to get to my DB's for the day, which in total cost us 80 pounds. They never visit us I think because we live in a 2 bedroom flat and because we only have 1 3 year old DS and they have 3 children.
I don't want to ruin my relationship with DB and his family but I am really starting to resent this attitude. Am I being unreasonble?
