Teddy bear, poems, does not make one romantic. You should be in the getting to know each other phase, likes dislikes. Get to the sweet stuff when you know it will be special to her. Not because you THINK it will be.
You screwed up, you are too clingy. Give it up, and break up with her. The tighter you try to hold on, the worse you look. Maybe in the future, you could try again.
