After a year of long-distance dating -- she was in New York while he was in Los Angeles -- this young couple decided they were meant to be. Sarah moved to L.A. to be with her man and the two moved in together. "I think we both realized it when we were cool with just hanging out in sweatpants together," Matt said about his relationship with Sarah. "And [we] didn't have to think about what we were going to do. It just kind of clicked." Apparently low-key works for these two because four years later they are still going strong!
