Admirable.
When me and my kids dad finally threw the towel in I got nothing but debts and a debt management plan.
If she stays in your family home presume you have somewhere to go then are you thinking maintenance for the children aswell as bills??
I know previous ageements have involved alternate contact, buying of clothes, trainers etc.
I suppose as soon as you have yourself straight you’ll be able to budget it all in better.
Good luck
