Thinking of paying off my fiancé’s credit card debt as an interest-free loan … smart move?

Once we’re married, we’ll definitely combine things! That’s why I’m eager to help now, even though we’re still engaged. If we work as a team, it should be easier for us both.

If you’re set on helping, just wait until after the wedding. Have him work on doubling payments in the meantime.

I’d suggest letting him pay it off himself. Tell him you’ll discuss marriage once he has his finances in order. Covering someone else’s debt is risky.
