I'm sorry, OP, it does sound like a lot to be dealing with so no wonder you feel a bit overwhelmed.
It might help to separate out the issues.
Your relationship break up- he doesn't sound worth your time. You deserve better. And actually, sounds like you need to be single and focus on yourself for a while.
Your housing situation- it sounds like you know realistically you have to take this house, so I would try to accept that and make the best of it, despite daughter not liking road and green windows. You know you'll be able to change the windows thanks to paint voucher, what about the walls needing replastered, is that something the council will do but you might need to wait for?
How old are the daughters who aren't talking to you? Have you got a friend in real life who could help you talk to them?
They do need to accept that you're moving. It sounds like the relationship, moving and your dynamic with them have all got muddled up and you're all feeling emotional and they're feeling resentful.
Maybe you could say something/ or write them a letter like
"Daughters, I know the last few months have been difficult and we're not in the situation we want to be in. I'm aware you had issues with my last relationship- in the future we will have to find a way to talk about things like that. But for now, it's important that you understand that we will be moving to the house with green windows, there are no other options so we will need to make the best of it. It will be much nicer for all of us if we can get through next few months showing each other some kindness and understanding as I know I'm struggling and I'm sure it isn't easy for you either...etc..."
