Of course there's more to it.
After his surgery he seems to have a permanent wet cough - it's worse when he lies down. That and getting up to pee a few times during the night was waking me and I would, understandably, complain. It was his idea to stay in the back room because it would infuriate him when I mentioned his nocturnal disturbances.
We have sex - not always in a bed room 
The attraction is still there - when he walks into a room my heart still beats faster. That has never changed. I was devastated when he was in resus when his initial surgery was delayed, I was told to prepare for the worst and I had to go home thinking he would die. He had aortic dissection type A and now has a synthetic aortic arch and aorta.
And since his huge personality change (not for the better) due to being on bypass (pump head) for longer than anticipated, I'm happy to be able to read or watch tv for as long as I like in bed,
because when he was getting 'back to normal', after surgery, he would not allow me to read in bed/have the light on or watch tv - which I had done before.
I've spent time cleaning my 'own' room from top to bottom today and it's now fresh and organised. He had suddenly got a bee in his bonnet because he'd bought yet another motorcycle helmet and there was nowhere to store it in his room because 'his' wardrobe was 'stuffed with your clobber' i.e. mine.
He has days when he's calm and affable, more or less his usual self but he doesn't seem to cope with the tiniest bit of stress - he completely blows up/overreacts and freely admits he spends a lot of time apologising to family and friends for things he's said and done. His addiction to spending money online on stuff he doesn't need - says he's aware of it but is compelled to do it, began as soon as he could access his iPad after the op.
He also now likes to 'hold court'/be centre of attention when in company - something he hated before his surgery.
So it's just an adjustment we're still trying to navigate. Never a dull moment.
I had some clothes in the spare wardrobe in the back bedroom because way more than half of the space in the main bedroom was crammed with his clothes/stuff. The main point is - his 'shit' takes up more than twice the space of mine - he had no idea. He's online now ordering 'storage'. He still has clothes from the day we met. He has tons of clothes (and nothing to wear). 
Some would say leave. Some would think it was scandalous to leave a parter after life changing surgery/major illness.
As a pp says - having separate bedrooms can save a marriage.
Is it normal for blokes to have more clothes than women? - And still complain of have nothing to wear?
