I know how you feel. Luckily I've had parental support. Not needed anything from them in 20 years but they have been there for me now when I needed them to help me get back on my feet.
Do you have kids? Can you claim Universal credit. Go on entitledto or turntous to find out what you can get.
Work on a plan. I've been back with folks working on things, the situation was dire especially when it came to renting, the checks are impossible to get around with low income, every avenue I tried was a one way street but I'm hoping I got there in the end (find out today/next couple of days)
You don't have to leave immediately. If worse comes to the worse ask for a divorce and for the kids/financial reasons he should leave. You have time to plan and think of options if you are ready to go. Maybe the threat of this will kick him into gear to try harder. Who knows, but change is very hard for people and we all tend to fall back into our natural patterns.

I'm in Bored's position. I feel like it's me that is trying to sort the arrangements out and how we should continue and raise the kids. My ex I think, not sure is hurt, angry etc. I have zero feelings for her after 12 years and just split. Says everything really. I'm now treating, at this stage, our relationship like a business. Being pragmatic, not being lured into an argument, which she loved to do, getting me riled up while she then looks like the victim. She's still trying. What she doesn't realise is I've seen how she was with her ex and their kids. She would love to subtly alienate me, she is now desperate for me to have kids 50% of the time because she is now working and I used to deal with most of it for the last 3!years especially and did my share if not more before that.
We're navigating choppy waters but I am putting all feelings aside, she dislikes me and me her at this early stage. She says let's be normal for the kids, but then blanks me when we've had to be at birthdays and things. Literally walks past and blanks me.
I have no doubt things will get better, but as Bored said, it's how you deal with things and get on in the future, which will take time but both parties just need rot behave like grown ups. Part of being separated for me means I don't have to get into arguments with her any more or justify myself, which I had to do a lot. I've told her months ago that I won't be responding to anything unless it's about the kids.
It will be tough to start. I could have just jumped on a plane and flown to Mexico rather than face telling my kids. They started to pick up on things though, I was on sofa cushions in the living room, trying to get up and put everything back to normal before they got up. They picked up on it though.
