He missed her when he couldn't see her and yet, when he did see her, he couldn't control his emotions, and it was obvious that she was also interested in him.
He wanted a clean break.
He knew that once he entered the army, it would be perceived by all that he had undeniably handed his life and fate over to the country.
He made a decision that night when he was sending her home.
He apologized to her for missing their previous date, and then he arranged with her a second date to go to a movie, even giving her his contact number.
But she was innocent to the game he was playing: He didn't want to start a relationship with her—he wanted closure.
The phone number he had given her was fake, and he had no intention of meeting her at the movie they had planned to see.
Rather than simply trying through will power to cut off any feelings that she had for him, he was forcing himself onto a path of no return.
