Here's a new dating rule. No matter how good a date was . . . if you don't hear from the guy within three days, it's OVER.



--A new study out of Germany found that a guy will make it VERY CLEAR if he likes you or not depending on how long he waits to call after a date. And if it's three days . . . he doesn't like you.



--The study found that 33% would call someone the next day if they liked the date, and 44% would call on the second day. Only 5% of guys say they'd wait three or more days to call if they thought there was a future.
