Hi BigK. Did she ever show you that she felt the same way for you? I'm sure as friends, she has hinted to something like "No, let's just be friends," or "Getting into a relationship can hurt our friendship..." etc.? Does your teddy bear say "I Love You?" If I were you, to play it safe, buy her a plain teddy bear with a yellow rose. That way, it's more of a friendship gift rather than something to shock her.
Hope that helps.
