I feel strongly that this song is simply about the guy feeling so crazy in love with a girl he met. She may be a close friend. He dreams of her. He "falls down", or stumbles, when she is around him. "Cupid's bow, it stung" is self explanatory, it means Cupid shot his arrow and he knows this girl is the one for him, he is in love. He says he can't contain the control she has on his soul. He is helpless in his feelings for this girl, he cannot help but to have these feelings. It's almost as if loving or having feelings for this girl comes natural, regardless of what he wants. "When all is said and done, I know you're still the one" simply means no matter what, in the end, she is "the one" for him. That is how I interpret it all.
