He smiled hearing that.  He wanted that too.  He needed that too.  He had to make it happen.  He decided then and there to dedicate his life to her.  This time he wouldn't choose anything without her.  He wouldn't choose anything over her.  Her words meant everything, indeed, to him.  He wanted it too.  He walked with her enjoying the feeling of being a couple again.  He had succeeded in winning her heart and she had made her decision quickly.
