Breaking Up is Easy to Do if You Use Specialized Candy
Clean Break candy is a project designed by a graduate student named Kathy Mueller. These faux candies are have a popping aesthetic that just scream "it's not you; it's me." Each variety has a snappy slogan and comes with a card that you can fill in with an applicable break-up reason. Also, bacon and chocolate always go well together.
Even though candy is usually the best idea, I suggest you just sit the person down and talk to them for a while. That tends to work even better than bacon.
