"I'd been told that he had been created—literally created—just for me, as my 'perfect other half.'" This suggests that the speaker initially believed Dylan was the ideal soulmate designed specifically for her. She had high expectations and possibly an idealized view of their connection.

However, she quickly questions this notion by saying, "Let me tell you—if Dylan was my perfect other half, then I needed to give my first half a serious look-see." This indicates a moment of doubt or realization that Dylan might not be everything she thought, prompting her to reevaluate her feelings and expectations toward him.
