Horrible with money

So me and my fiancé are supposed to move out to our own place on Monday. He doesn’t know how to manage money at all. His hours have been cut. Which leaves it up to me to pay for food, gas and etc. I’m just so worried that he will not manage money and we will be late on bills.

I’m the type of person that has my money managed well because I get anxiety if I’m running low of money.

I’m just not quite sure if it’s smart to move in with him or not.

What should I do? Is there any way I could help him?
