Backstory: MIL is actually a step Mum in law. She doesn't like my DH very much - married his DF when DH was was 8 after his DM passed away. Fast forward 28 years - she has 3 DSs of her own from before her marriage to DFIL with DH aged 8 attached. She does not have a great relationship with any of her DIL or DSs and so doesn't spend the holiday season with them.
Whilst I like both DFIL and DStepMIL, they don't do any of Christmas the way my family do i.e. tree, presents, traditional meal. There are no decs or anything. For the last 6 years, we've spent one Christmas with them as they don't really seem to want to celebrate it. One year we did spend it at theirs, she produced a lamb stew for two people with five around the table, and when people ran out of food heated up some frankfurters anf gave us crackers and cheese. DStepMIL is just not very keen on the whole thing, I am, and here in lies the issue.
This year, I said we'd love to see them for the holidays but know that DSMIL finds cooking for us, them and our step BIL a chore. So I asked if it would be a good solution for us to come with all food and organise everything as she knows I love to cook.
She was happy with it and bragged to friends that her DIL was cooking; I emailed her a couple of days ago to make sure she had the basics of a couple of sieves etc and then she tells me that I am making too much fuss, doesn't see the need for yorkshire puddings, gravy, christmas pud etc etc etc. I had emailed her just to let her know what I was planning and wasn't asking for any help! She had offered to make a couple of items for the day and is now saying she thinks I am making too much food for us and so isn't going to make her bits, despite discussions about leftovers.
Should I try and tone it down, or just bring and make everything as planned?
