"Besides, now we're both wearing the same amount of clothes. Equal." She didn't want to tell him that she loved him - she wasn't certain she did (if only because she wasn't sure how one determined that fact) - and because she didn't want him to freak out and fly out the window.
But she did want to show him. She could show him through actions instead of words.
