Hello @Admodean I hope you managed to get some sleep and are starting to feel better. Lots and lots of fluids for you. On practical nursing matters as you may not be thinking straight:
Complan if you can get it will help build your strength back up (deliveroo or whoosh or your mum could get it?)
Dioralyte if you're shitting a lot , to replace vital electrolytes.
There have been a lot of very kind and sensible posters on here but others have been pretty harsh and , frankly nasty given your current delicate state. I've been in your position of being piled on by people in Mumsnet who seem hell bent on trying to make you feel even more shit and blaming you for everything. Please do put them to the back of your mind.
To Your original question 'does he love me?' , I think probably not. I'm sorry. At best he's breathtakingly, inexcusably selfish, at worst he's breathtakingly, inexcusably selfish and exploitative using you as an unpaid skivvy. Neither is good for you.
A marriage should be about working in partnership, each bringing strengths and weaknesses, each doing things to make the other happy, comfortable, feeling safe and loved. It's about sharing the load (which comes in peaks and troughs for both of you). It's about having fun together, about intimacy, about you two together against the harsh world outside. It's about devotion, loyalty, patience, caring, and love. That may sound like a big list, and it is, but all those things need to be there for a strong equal partnership to survive.
I think what's happened here is that you've been shoring things up for some time and that this illness has been the catalyst. You can't do the shoring up at the moment and it's all fallen down. You are the main (only?) one making the emotional and logistical effort and now you can't, the paucity of his contribution to your marriage is starkly exposed. And your ability to just ignore it and get on with it is depleted. So here you are. It's shit, and I'm sorry.
Focus on getting well. Gather your friends, family and allies to help with that and to help you as you recover. People who love you will step up. And to those saying you are a drama queen and they've coped with worse, well good for them. I've got a chronic illness and cope with it but by lovely DH looks after me when I'm ill, every time, he alleviates my suffering, not adds to it. That's the bar. That's what being married is.
Once you are better make plans that centre around your needs, happiness and future. If he decides to change and be part of that, maybe you'll let him, Maybe you won't. But right now, get well, get strong and remember that the world is stacked with decent, kind people who are just waiting to be in your life.
