Oh, I so sympathise with messy house problems. I actually have a Roomba that hoovers for me, which is the only way it gets done. I bought it some 5-6 years ago, and it was way worth it. I wish there was one that could wash bathrooms as well. And do laundry. Seriously, I need that robot from the Jetsons. I have a horrible catch-22 in that I tend to get colds if the cleaning hasn't been done, but I can also wear myself out doing the cleaning. But that is less problematic than being sick for weeks; at times I've lost entire seasons to one cold. Deciding to take it easy in preparation for a hard work week like I did yesterday is rolling the dice.
crikey, I understand your situation from both sides: my DH has had ME since I've known him, and goes through good/bad spells. And I'm struggling with my own issues right now. DH sometimes gets cross with me for 'ruining' plans when I'm too tired to do things, and I sometimes get cross with him for doing what I see as 'wasting' energy on less important things (like how he can be up late designing model train layouts and yet somehow can't manage to scrape DD's uneaten food into the compost bin and leaves me to do it when I get home from work).
One thing to keep in mind is that the fatigue is NOT logical. For some reason unbeknownst to me, one trip to a store, even if it is only 15 minutes, is just as exhausting as an afternoon hiking. Taking the day off work except for a single 30 minute Skype meeting will leave me almost as exhausted as if I'd gone in for an 8-hour day. It makes no sense.
Like magso says, you two probably need to have a sit down and try to understand each other. Ask him to tell you what his limits are, and see if you can figure out things that he can do within those. You probably need to set up some method of communication such that he can let you know if he's gone past his limit and isn't going to be able to do things he planned to. Sometimes my DH sometimes literally can't make words, and I know if I talk to him and he mumbles back, that it means to throw the day's plans out the window.
One of the things that I had to learn from DH when my fatigue issues started was that it is counterproductive to put all my energy into what I thought was 'most important', meaning things I found enjoyable simply fell away because I couldn't justify to myself spending energy to, for example, work on my crafts when I didn't have enough energy to clean the kitchen. It sounds like you might be having a little of my mindset there. Even with less energy, one still deserves a full life, so it can't always be the 'unfun' things that get done.
Your happiness is important too, and your DH also needs to realise that he has to save some spoons to work on your relationship. It can't all be from your side. Have you read the spoon theory? Has he? It might do to use it to open a conversation by showing it to him and asking if that is what it is like for him.
