Lyric discussion by baradakis 

There is a new 'that' in every verse, he says I would never lie to you, I won't forgive myself if we don't go all the way, Tonight; I'll never stop dreaming of you every night of my life; I'll never do it better than I do it with you; and when she says the he'll be screwing around sooner or later, that is the 'that' for the last verse.
Steinman is a great lyricist, too bad he couldn't sing.

Hit the nail right on the head, it's obvious, although both Meat Loaf and Steinman were still worried it wouldn't be clear to some people and cause confusion.
