I think it comes down to some communication and some practicalities. When I'm in pain I can be very messy because I can't get up and do things. As such I need a bin next to where I'm sitting. My OH doesn't think to bring one because your partner can't think of everything or work out what you need sometimes. It took a while for us to work out - I just needed a bin nearby during periods when I wasn't mobile. I find it harder the other way round, being female - because my standards aren't kept up in the house! It drove me mad seeing the kitchen sometimes - nothing cleaned properly or done my way. But - I got to just accept it and think it's just how it is. I've also had times where we've had a row because I've said I'm in pain and OH didn't behave any differently and still nagged at me about something. Which is harder to take when you're in pain. The other person can hear it but can't understand what you can't find the words for - ie - I'm struggling right now so can we just keep things nice please.
I don't know if you're still in this situation - but - I don't think your partner IS independent of you. He's not managing and is not telling you. So he just gets messy - it's pride - rather than say can you help me with xyz,
Have a sit down talk. Say we need to work out a routine that works for both of us so we don't argue. And we need to work out what I need to help you with and what practical things will help you be more independent and make me less tetchy about mess. So a bin near a chair is one thing. Get some aids and gadgets. I now use a powerchair round the house which has made a huge difference. And have "litter pickers" in every room.
There is also the emotional side of coping with pain. It can get depressign and people stop caring about daily things. So he maybe needs to have an outlet like someone else to talk to about it once a week. Counselling maybe.
As for doing things on your own - just do it. I don't expect my OH to stay at home all the time or take me everywhere. He does some things independently, goes out (not at night but during the day). We have to co-ordinate in case it's a day when I need him to do something here - eg if there's a medical visit. I have ring doorbells so can answer the door from my phone if necessary though. Then we plan when we're going out together.
At a guess I'd say he is hoping you will think of things so he doesn't have to ask. Sometimes it's really hard to ask for help. Going out together is nicer if you don't do it all the time. Make a kind of date outing - eg going to a cafe together - or out for lunch. Not just routine stuff like food shopping.
Maybe you need someone to talk to as well. But get a routine sorted between you. One day a week you go and see/go out with a friend. Find some new activity you can go to together.
It's not easy for you juggling everything. But one thing I will say it is much much harder when you both get something wrong with you! If you suddenly had a serious condition as well for example. We've been there, and I had to get very organised and get some help organised temporarily and we were both stuck at home for weeks as he couldn't drive for a while.
You can also have your own spaces in the house. A bedroom is my study area/office. We phone each other from different parts of the house to have some space sometimes.
