Ring as a gift

... you.

If someone gave you a jumper that was the wrong size, you wouldn't give it back to them to take to the shop to sort out would you, you would go in and exchange it yourself.

There is a difference between a jumper and a ring. The ring needs to be adjusted for a price of almost 90 pounds. So, how ok is it to give a gift and mean "I've paid for the ring and you have to pay yourself for it to be adjusted to a correct size"?

If you are on here I am assuming you are already engaged? Did he get your engagememt ring in the right size? Why didn't he just go for the same size again?
