<prompt> Human: I recently opened a credit line for an engagement ring she said yes! but now Im stuck with a significant monthly payment for 12 months. The loan is interest free so long as I make the minimum payment online. I have the money to pay it all off at once, but I was advised by a friend that even if I did have the money, its better to not spend it all at once - referring to the fact that if you have more money on you, you can invest and have it work for you yada yada yada.Personally, I rather just pay it off at once and not have to worry about these monthly payments, but Im not sure if that is the best financial decision. What does rpersonalfinance think?  <response>: Yes, pay if off. Dont listen to broke people.You are thinking about this correctly.
