Nah
There is always the method of absolute refusal when you are being broken up with. It is not easy to execute, but if done right you can confuse or significant other to the point that they change their mind and end up taking the break up back.
Take this person for example. They just kept saying “nah” and rejecting their significant other’s attempt at calling things off. Sometimes the other person in a relationship can get confused, emotional, or just a little lost- and if you’re really meant to be together you can just “nah” them until they come to their senses.
