What happens to adults without spouses?
IME and IMO, they will try and and palm them off onto someone.
When my 2 DD were very young, I worked 3 days a week, and we had a 2 bed house. I visited a great aunt in hospital (she was a great aunt by marriage, my grandad's brother's wife who was married to him, for 9 years before his death.) She was in hospital for 4-5 weeks after bowel surgery. I went 4 times in about 5 weeks. A 60 mile round trip.
I didn't know her massively, but had met her a dozen times or so since she married my great uncle. I visited her as my great uncle had died a few years before, and they'd had no children, and she had no family except 2 nephews who she rarely saw, and who lived 50 and 80 miles away.
On my 4th visit, the Sister on the ward she was on, took me aside and said 'your aunt is due to be discharged soon, we need to talk about her post hospital care package' Long story short, she assumed because I visited 4 times, (and was her ONLY visitor except one male ex colleague who visited twice,) that I would take her home with me and look after her and be her carer. (OR move in with HER and be her carer!) 
I didn't know her that well, she had only been married to my grandad's brother for 9 years before he died (they met in their 50s,) and I had 2 children under 7, a job, and a small 2 bed house.
I said I absolutely can NOT take her home and be her carer. The Sister said 'well she needs SOMEone to look after her, she can't be on her own.' I said 'well I'm sorry, but I can't do it. I simply can't. I have a job in my town 30 miles away, and 2 small children. She has 2 nephews in their 30s, her deceased brother's children. Ask them!' The Sister turned her back on me, and walked off.
I went home with my kids, and rang my aunt's house a couple of weeks later, in case she was home (no mobiles then,) and she answered the phone, and said she had a 'home-help' now, and wanted nothing more to do with me as I had abandoned her. 
I said 'what about David and Peter, your nephews!' She said 'you can't expect MEN to look after older family members for goodness sake. It's the job of the women in the family. Anyway, as I said, I'm done with you now. You let me down.' Then she put the phone down on me! 
I was gobsmacked. I was the ONLY one to visit her in hospital, no-one in the extended family bothered, and her 2 nephews didn't either, and yet I was a pariah, for not letting her move in with me!
So yeah tl;dr, the NHS will try and palm single adults who need care onto any relative who is soft enough to take them. And it will very likely be a younger WOMAN they will target...
