A song consists of conditional sentences

This is one of my favorite songs from a famous R&B singer, Usher, named "Separated". This following video bellow is made by someone, and i just pick it off from YouTube to my blog. The reason why I put this song, not only because it consists a lot of conditional sentences but also because it is a beautiful love song. Though I consider this blog as "Junior High School" blog, I hope they won't judge this post as "a love song for adults", but try to consider what the song consists of (the conditional sentences)

Here the song with its lyrics, enjoy yourself.!!!
