Here’s a classic idea that’s always popular! Buy your girlfriend a heart shaped box of chocolates and replace one with the engagement ring. They may be surprised that you’ve gotten her such an inexpensive gift, until they find that diamond! Another idea is to buy a bag of candy hearts and find one that says “Marry Me”. Share the bag of candy with her, having the marriage one hidden in your pocket. When she’s not paying attention, slip it out and say “This one is perfect for you”, then immediately follow on one knee with the engagement ring in hand.
