When you see him, your heart beats faster. When you're around him you get butterflies in your stomach. When he smiles, you're heart just melts away. When you talk to him, you get really nervous. When you love just hearing the sound of his voice everyday. When you're fascinated by the way he looks when he's laughing. When you feel that pit inside you're stomach when you get close to him. When he walks into your class and you just stare at him like he's the only guy on the planet. When you wish you could be around him all the time. When you think about him every single minutes of every single day. When you're obsessed with him. When you dream about a future with him, and what it would be like. When you imagine being together forever. That's when you know you're inlove.
