"There's only one girl in the world for me" means that there is only one, and all the ones that don't work out, don't matter. There's plenty of fish in the sea and one of them is bound to be his.
Why settle for what's around him (in his town/etc.), when he could scour the whole earth in search of the woman he loves.
Don't settle. Choose wisely. Enjoy your time in search, and when found, enjoy your time together, because you found her. Don't let go. You'll know.
