Re: Making it on your own as a couple..
First would be to work on a budget...to understand that you will now have a budget and would need to lay our all your expenses. Both of you would need to be on the same page.
Second, learning how to pay bills on time. Probably we haven't done too much of that before we got married so putting that on our schedule.
Learning how to put away some money every month or so. Depending on the income, you will need to come up with an investment plan, especially if you have loans.
Learning how to prioritize. Like is it importnat to pay off a credit card that month or to buy the new dinner set.
