Thanks for all the advice.
We will have paid off most of the debts by autumn so I'm more worried about the next few months, after that things will be ok.
I think I'll try doing a 'trolley' with the same things on Tesco and on Asda online, without actually buying them, just to show him the price difference. Trouble is, he's insisting we should collect clubcard points so we can afford treats, we're saving all our points towards a holiday at the moment.
We don't want to downsize, we want to start a family as soon as the debts are paid off so it'd be silly moving somewhere smaller, and this house is about the same as a smaller house usually would be round here anyway, it's very cheap for the size. Also, moving would mean that we'd need a deposit, first months rent, agency fees etc up front.
Does anyone know if you can end a car Hire Purchase agreement early? That's one expense I'd like to not have any more.
I'm quite pleased at the moment because I'm changing jobs and will be paid weekly, I've just done a very detailed weekly budget, which should cover everything as long as we don't have any large unexpected expenses.
