In honor of the new Jennifer Aniston-Vince Vaughn flick "The Break-Up," which opened Friday, Universal Pictures and Budweiser have declared June 2 "National Break-Up Day."

Do Universal Pictures and Budweiser really care about the state of your relationship? Not so much. But this obvious tie-in for the movie - which is opening to mostly bad reviews - might actually inspire people to abandon good loves gone bad.

According to the official Web site nationalbreakupday.com, "National Break-Up Day is the perfect excuse to bail yourself out of that sinking ship. It's a day where we can all stand undivided nationwide, and with one voice...get divided."

But how do you know when it's really time to break up?

Dr. Herbert Robbins, who specializes in relationship therapy and counseling in New York City, said it's time to break up when you start feeling unhappy in a relationship.

As simple as it may seem, Robbins says happiness measures the strength of a relationship and more often than not, couples grow unhappy but try to hold on to a relationship that is exhausted and obsolete.

"People are experts at self-deception," said Robbins. "They repeat the same mistake over and over again, and justify it each time."

If you're in abusive relationship, separate immediately, Robbins warns. Otherwise, he suggests receiving counseling, not necessarily to mend a relationship, but to better understand why you chose to be with your partner.

If you and your significant other are truly unhappy, Robbins says there's good news and bad news. The bad news: you're unhappy. The good news: you're unhappy. But what’s good about being unhappy?

"Feeling pain means you still have values, and can get help," Robbins said. "Once you become numb to pain, there's no hope."

Robbins says a relationship has the chance to be repaired when the couple fights over trivial matters and the issues are not fundamental. Oftentimes, this has to do with a communication deficiency between the couple.

"You have two ears and one mouth, which means you should listen twice as much as you speak, and you have teeth so that you can bite your tongue before you speak," he said.

But when the issues are more serious, sometimes it's time to say goodbye.

New Yorker Natasha Gibson, 21, who went through a tough breakup last year, said overcoming the split was challenging and that the deteriorating relationship was a struggle for her.

Nevertheless, she said she's thankful for the experience and advises people to "move on and live life."

"I just moved on and didn't think about it," she said. "The hardest part is the beginning, but once you realize there are more people in the world, you realize everything's going to be OK."
