I'm afraid I am not the Oracle ( which was always wrong anyway ) . In a situation where a couple split up, one spouse is working but the other is not, that spouse is normally expected to take steps to obtain employment.
The Courts will usually allow a fixed period of maintenance as a bridge to self sufficiency. How long it is depends on the facts each case. If one spouse was a medical student with two years to go to qualification, then two years might be appropriate. It may be reasonable to expect your husband to work part time and yes, that would reduce your SM. What is a virtual certainty is that, if there is no good reason why your husband can't work, you won't have to pay him maintenance for more than a clearly defined period. Sorry, I don't want to go further than that. This is the principle and how it applies to you is something you need to work out.
As to assets, the law is notoriously uncertain as to how to treat short marriages. If I were arguing for your husband I would cite the famous ( or imfamous depending on your point of view ) case of Miller v Miller where the wife got £5 million for a shortish marriage between 4-5 years on the basis that the husband's shares had increased in value while these two were joined in holy matrimony. Not all that much different from your situation. I would also quote Lord Nicholls who said that the wife has a claim to a share in the
marital home even for a short marriage - you can google the judgment and read it if you don't mind risking being bored to death.
But against that, his contribution seems to be virtually nil, or even negative. You provided the house in the first place, you paid the mortgage, you supported him,
he did **** all, and it seems to be wrong in principle that he should get more than a small allowance to buy some basic necessities for a flat of his own. On a personal level, I prefer the latter view, but you can't treat men differently from women, now, can you ? Well you certainly can't treat women differently from men before someone descends on your head from a great height.
So there are arguments both ways and it's no help for me to say it may depend which judge you get. He wouldn't get much if I were the judge, except possibly a few well chosen words.
