What is the reality of divorce with DC?

[Mamamamamia]

Im beginning to get my head around the fact that i need to leave my husband
Ive been trying and trying to wait and see if things will change - but its clearly not going to.

My question is : single workig mum- whats the reality?
I myself, was raised by a single mother: but she never worked - we had no family to help us and we were dirt poor.
I would hate this for my DC
ive worked all my days and have a job i enjoy , i get better than min wage, good benefits and overtime- but i cant see how i would be able to continue to work due to my shift pattern?( crazy long /night /day /never the same day..)
I can go move closer to my elderly DM? But asking her to mind DC for as much as i need is a lot to ask
Has anyone continued awkward hours and been a single mother? Were you able to buy a home? A little holiday? Not skrimp?
Give me some hope/home truths ...

I’m a single mum of two. Financially it’s not been easy but we get by and we’re all much happier than when me and their dad were married.

There is help out there for lone parents- I get tax credits but it's now Universal Credit, there was up to 80% help with registered childcare costs, 25% off your council tax, if you're renting then the equivalent of housing benefit is incorporated into your UC, there's always maintenance - the CMS calculator can guide you there, and entitledto.com for the other stuff. Life is too short to be miserable and kids are affected by unhappy parents

Left Ex over 2 years ago and went into a rented house. I work 30 hours and get Universal Credit, 6 weeks leave and put DC in breakfast/after school/ holiday club if needed. Universal Credit pay up to 85% in arrears for this.
I can run a car, save a little and the DC have clubs, classes and a nice standard of living. ExH doesn’t pay maintenance and see’s them EOW. I’ve just got a little job when they are away. We’ve got a holiday booked in the summer and get a few day trips throughout the year.
We don’t have a TV package or expensive phones. I don’t drink or smoke or go out very often socially but I get an odd takeaway and don’t feel like I’m missing out.
