Cover art for You Had Me at Hello lyrics by A Day to Remember

It means that he's falling in love again, even though he swore he'd never trust another girl with his heart. But she's different, she changed the whole way he thinks about love. She sort of healed him in a way. He misses her to death when they aren't with each other and i think he's realizing exactly how fast he's falling.
