5 percent rule 

After you break up with someone, you are not allowed to mourn over the loss for more than 5% of your time being with them.

The 5 percent rule goes like this: you can mourn over the loss of a boyfriend or girlfriend for no more of 5% iof the time being together (as previously stated). FOR EXAMPLE, if you dated someone for 60 minutes, you can mourn over your tragic loss for 3 minutes (if i did my math correctly)
