Who do you vote for op?
Are you genuinely shocked this is how many people live op?
When I was raising dd especially after I could no longer work due to disability this was my reality.
When I first split from ex and was on benefits at a time when cm was deducted - even if he didn't pay it - I had several days/weeks when I managed on one small meal a day in order to feed dd.
Even when I was working I had all the bills come out the day after pay day to ensure they were covered. By the last week of the month we were managing on what we already had in food wise pretty much, I'd only buy minimal fresh items like milk.
I'm good at managing a tight budget after decades of practice, but even I can't magic up money if my benefits/wage was cocked up, or an emergency came up like a power cut rendering the freezer contents unsafe or a sudden hike in rail prices meaning I was stuck for fares for work.
For you to be as shocked as you are I can only imagine you have led a fairly...sheltered life!
Which is lovely for you but have you never considered this is why we have food banks and people trying to change the current welfare system etc?
I can't know how your autism affects you so I hope this comes across ok. Could you learn more about people in this kind of situation generally? Would that help you to understand a bit better?
Many of those using food banks are needing to do so regularly for months, years.
People don't generally discuss their personal finances out of personal pride and also it seems to be a bit of a British thing it's considered rude.
But if you were open to it you could discuss general things like benefits, food banks, poverty levels, how these things are being addressed (or not!)
You're not married? Yet you are dependent on your do not only financially but in terms of financial management. I would urge you if at all possible to learn to manage your own finances and if possible to earn more. If earning more is not possible then you at least need to safeguard yourself for when - not if - your relationship ends. It won't necessarily end as a result of you splitting up, at some point one of you will die and in all likelihood he'll die first because women tend to live longer so you need to have certain protections in place.
Do you have dc? If so even more need to have protections in place.
You never know what's around the corner.
At 29 I was married, working, decent pay, healthy
By 35 I was divorced, disabled, unemployed
Life can turn on you without warning.
