Going the Distance (2010)

Erin has just six more weeks as an intern at the New York Sentinel before she returns to San Francisco. That's fine with Garrett since he just got out of a relationship. But their relationship blossoms and it quickly becomes something that they can't just drop in six weeks. They admit to wanting to be boyfriend/girlfriend just on opposite coasts. The distance wears on them, as with their nay-saying friends and sister, and soon they are forced to either break up or come up with a solution that has them living in the same city.
