I'm pretty sure the chorus is wrong. It's "Falling in and falling out of love." You can hear the "v" sound before the next line starts.
Other than that, I agree with wiggin and samwalton. It's most likely about how the "you" in the song walked out on the "me" because of troubles. The "me" is singing about it, saying that the "you" should not have let those troubles come between them. "me" says "Don't leave me, I need this," revealing he (?) still wants her (?).
