OP what stood out for me here is this:
I've said on the phone I would like him to come home but he's said he can't but that was earlier and he said I would be ok and to just enjoy the house to myself
Even if you are not deathly ill, he is being very passive aggressive by responding with "just enjoy having the house to yourself". Because if you don't enjoy it (and you won't, you're ill) then he's making it your fault that you couldn't 'enjoy' his absence.
My husband did this sort of shit for many years. I only twigged to what he was doing 12 months ago when I was so ill I ended up in hospital for 5 days. I called on the first night while still in the ED (after being given fentanyl and IV antibiotics) and he refused to come home from a conference and said "just get better and enjoy the peace and quiet". Like fuck off - he knew I'd been given proper pain relief and since when are hospitals quiet?? (FWIW we've been in marriage counselling for a year now and he's also having intensive counselling to deal with his PA and narcissistic behaviour - it's a bit better but by god it's taken a lot of work.)
Maybe read up on PA behaviour when you're feeling better and see if any of it fits.
Also (and I say this with love) have a think about whether or not you might present symptoms/illnesses as extremely severe even if they're say a 6 or 7 out of 10, not an 8 or 9. Because this will feed into him feeling justified about being PA or not taking you seriously. I had to be very honest with myself and realised I had done this several times in the past (in part because he completely ignored any discomfort I was feeling unless I presented it as very bad, but still it wasn't helpful behaviour from me) and we now use a grading for pain when discussing symptoms eg 6 is 'this hurts quite a lot and I might cry if I don't get some pain relief in the next hour or so", 7 is "this hurts a lot and I'm about to cry", 8 is "I'm crying". We don't discuss 9 or 10 as I can't speak by that stage
. I'm not saying you need this, just sharing something that has worked for us (I have a couple of chronic health conditions with varying severity of symptoms).
