@MarshaMelrose Unless the station OP got off at was a busy city centre one, then I doubt very much that there would have been any taxis there at that time of night! So she would have had to ring one up, but again, unless OP lives in a very large town, or city, it would be very unusual for a flag me and stop me proper taxi cab to be working in her area.
So that would mean ringing a taxi (and not an Uber if they were around then - just becoming popular in the UK maybe - as their drivers have no-where near the same amount of training and safeguards as proper taxi firms {where you have to ring up and book your taxi in advance} drivers' do). Most smaller - one town - taxi firms will pick someone up at 11.30pm - maybe 01.30am, if you are lucky, however that would have either had to be booked much earlier in the evening, or when one of their taxis dropped a customer off, at say the station, earlier.
So on being let down by her idiotic DH, the OP would have had to find a firm of taxis that were still open (which could easily be impossible) and ask them to come maybe a 20 minute, or 30 minute, or 45 minute drive to her railway station, to take her home to a property a 5 minute walk from the station!
They would have either laughed uncontrollably at her request, or charged her an absolutely exorbitant- but probably still fair - fare, for doing so. I am not up to date on the rules amd regulations for taxi firms, but it might even be that they are not allowed to choose what amount they can charge, and in that case it would be a firm no from any that she could find to answer their phone in the first place.
By the way, unless it was a very busy station with a manned taxi rank (and maybe even then), if I had been in the OP's shoes - or rather, on her crutches, I would have been too embarrassed to ask a taxi to take me on a 90 second taxi ride - but that doesn't mean she shouldn't have asked one if available, because as others have said, you can be raped and murdered within 50 yards of your front door if there is a sick enough individual hanging around. Unfortunately, more and more of these evil men (this sort of crime is inevitably carried out by men) seem to be crawling out of the gutter.
@Tryhard87 I voted that UANBU, because it was not about hanging on to a grievance that your DH should have given you a grovelling apology for 4 years ago, and done some spectacular making up for - hopefully he did that the next day, but not with sincerity it now seems? You are not being unreasonable for being upset all over again because him finding it funny now, 4 years later, shows that he never really understood what you were upset for in the first place, so any apologies he might have given at the time were worth nothing.
That makes it very relevant today, and although I normally hate vulgarity, some mumsnetters say the phrase
"I would have ripped him a new one"
(I presume they are referring to a man's anus) and in this instance I could not put it any better myself. He deserves having a new one ripped, and to have to defecate through a straw for at least a couple of weeks...
