Sorry to hear things aren't good for you, OP.
Feel a bit bad about answering the question- but you did ask.
Dh and I have been together nearly 35 years so plenty of time to consider the question, plenty of time for him to show who he is.
When we had only just got together I was working in the countryside; he and another worker's boyfriend came up for a party and both arrived while we were still at work. When we got back, we found that dh-to-be had gone into the kitchen and introduced himself to the cook and started helping with party preparations; by the time we'd finished work, they were all playing netball outside. The other boyfriend in the meantime had gone into a strop because his girlfriend wasn't there to meet him and gone off to sulk in the pub.
Another memory: dd had been admitted into hospital and doctors suspected abuse (turned out later to be genetic disorder). I had sat there all day desperately worried that something serious was being missed and feeling myself cold-shouldered by the staff. Dd was in pain and frightened. Dh in the meantime was working long hours and had no transport. No relatives or friends who could come and cheer us up from anywhere. Dark miserable evening, rain persisting down. And then dh walked in with 6yo little brother, both dripping wet, but with big smiles on their faces. He had finished work, collected ds at CM, kept him amused and happy (days before iPads) on two buses and a walk through the rain, and here they were, with a long journey back ahead of them, but cheerful and uncomplaining and ready to think about somebody other than themselves.
And as a third memory: when I was struggling as a carer to dd and my career was going rapidly downhill, he took a day's unpaid leave a week, with all that implied of having to scrimp and save, so I could do (mainly unpaid) work to build up my portfolio.
