Each verse mentions two things that the man would do for love, followed by one thing that he will not do. The title phrase repetition reasserts that he “won’t do that.” Each mention of “that” is a reference to the particular promise that he made earlier in the same verse. The four things he says he will never do are:
- “forget the way you feel right now”
- “forgive myself if we don’t go all the way tonight”
- “do it better than I do it with you”
- “stop dreaming of you every night of my life”
At the song’s conclusion, the woman predicts two things that he will do: “You’ll see that it’s time to move on”, and “You’ll be screwing around.” To both of these, the male emphatically responds, “I won’t do that!”
