I'm in love??? Help!!!

Emotions...

He's amazing. He's breath taking. I love him. I shouldn't love him but I do. He's my old best friend. He makes my knees go weak and my heart race. He's the only one to make me feel like this. My one fear was losing him and I some how managed to do just that. I can't get him off my mind. He's on my mind 24/7. I have dreams with and about him. I don't know why I feel like this. Friends say I'm in love with him and others say I just love him. I'm not supposed too. I really am so confused. Why do I feel the need to know what he's doing, how he's feeling, why he doesn't talk to me, why do I want to be in his life even after we stopped talking all together? I need help. I want him all to myself.... Knowing he's not with me or forgot about me makes me sad. I don't even want to go to my brothers practice because i know he's there and I don't want to see him cause I know I'll get sad and he won't talk to me😔💔
