I hope the surgery goes smoothly 🙏
He's an arse. Him not understanding, I can semi forgive as he not had surgery before and can perhaps be forgiven for underestimating the pain, exhaustion, incapacity etc as you recover. But the silent treatment, especially at a time when he should be considerate that you might be worried and nervous, is utterly unforgivable. Is he always so selfish? What was he like when you were recovering from labour and birth?
Those posters suggesting he pop out to buy new bedding and make it up for her - I'm getting the impression this is a total pipe dream unfortunately. But many, most, men absolutely would take care of this without being asked.
Also, having had a fair few operations under general and sedation over the years ranging from hour long procedures to 8+ hour surgeries, I need to prepare you for not feeling immediately ok for a while, even if your pain is controlled. I tolerate pain relief and anaesthesia well, but I will invariably have trouble sleeping for the next few nights after. It's almost like the deep sleep of sedation or anaesthesia totally knocks my circadian rhythm out and I'll sleep for 3 hours max - exhausted and uncomfortable But not able to sleep. You should be in your own bed with a supply of drinks, snacks, pain relief and a book on hand just incase.
Please don't let him coerce you into just getting on with things too soon to make his own life easier. You need looking after. If he can't muster enough love and empathy, I think you need to really re-evaluate things.
I get the hotel suggestions, and I'm glad you are prepared to advocate for yourself, but you honestly shouldn't be alone and it makes me sad that you have to go to this extreme in order to get the rest you need.
