Financial Advice (1 income) (How to stop spending)

Okay y’all here’s the tea, I’m a SAHM and my fiancé brings home about $500 each week with no overtime (with overtime it’s obviously more.)

We have a 16 month old, and I am due in May with our 2nd. We rent which is $875/month, and of course utilities on top of that which vary month to month.

We have a VERY bad habit of eating out and spending so much on food, and other non-bill things that typically we struggle by the end of the month to pay for rent etc.,

What are some things you have done or do in order to control spending and have enough money with just 1 income? Obviously we need to cut back on eating out BUT that is what we are struggling with the most...Any advice is appreciated.

(We also have to buy groceries, gas, etc., so that goes into account for our spending as well)
