Should I stop loving?

the first day I enter my school, I fell in love with my senior.. day by day my love for increase. I don't know if he likes me too. I can't get him out of my mind. I always think about him everyday no matter where I am. I always smile when I think about him.. he is a sagitarius & I am a scorpio. where ever I go he always there at the same place... one day I met him at my house. that day I started to know him as my cousin. I don't know what to do. should I stop loving him? should I give up? it's making my head hurt every time I think about it.
