DH having major surgery on 22 Dec and MIL has invited herself for Christmas

[QuandryatXmas]

Forgive me but I don't know what to do. It's not the end of the world as who knows what will happen with Covid in the next couple of weeks but I am feeling very anxious about this. Long story short - DH is having major surgery on 22nd December and MIL has decided she's coming to ours on Christmas Eve so she can help cook the Christmas Dinner and will stay until 27th Dec.
WTF - I told her we aren't doing Christmas this year as things will be so uncertain and that I'm going to buy new bed so I can sleep in the spare room so he can recover/recuperate in ours and so there won't be any room for her to stay. 'Don't worry about me' she says 'I can sleep anywhere and I'll bring a camp bed'.
Right, so my dilemma is:

1. Am I being a total bitch in thinking that me & DH will be totally exhausted and will just need a few weeks of adjusting and getting used to him recovering and that we really don't need someone else in our home to worry about.
2. Chill Out - It's his mother FGS. Just let her come round and maybe she could help out.

She is a nice MIL but a bit selfish i.e she'll be on the phone to me and the first 10 minutes will be all about her ailments then she'll ask how her DS is.

She seems to be a bit blase at to how major this is and I don't think for one minute that DH will be up for a Christmas dinner but I may be wrong - I've never had to look after anyone who's had major surgery before.

I've spoken to DH and he's said let her come round on Christmas Day and she can go on Boxing Day but he hasn't told her this yet. I will respect what he says but I don't really want her here at all so AIBU or practical?

Any thoughts would be great to read as I have no idea what the hell to do.

Hi everyone. Just a quick update as you've all been so kind. DH is doing really well although his appt with the surgeon has been pushed back a week, so we have to wait until late Feb for final results but I'm hoping it'll be good news. Because of what DH has been through, his brother got tested and has had an MRI scan and a biopsy and he has been diagnosed with prostate cancer too. At least we will be able to support him and he can see how well my DH has done. Good grief.

So please all went well OP.

Onwards and upwards.

good news! And actually good for BIL too, getting it picked up I imagine quite early with positive prospects and example of your DHs progress. All best for you all including MIL who must be very anxious again.
