Am i in love with my ex boyfriend?

Im only 16 and i know people say that you are to young to be in love but frankly i dont believe that cause age has nothing to do with love it all depends in what your heart feels, but the problem is i dont know what love really feels like but when i see my ex boyfriend i get erflies in my stomach big time! i love to smile when hes walkin next to me and i cnt help but smile! and everytime i think im over him the feelings come back but i dont flirt with him because we are just "friends" again when i want to be so much more then that! i wish he would give me a second chance i miss him so much hes the first guy that i actually thought i loved, everytime i was with him, everything was always perfect, i was always to shy to look in his eyes no longer then 3 seconds and i just cant get him out of my head and i constantly dream of him what does this mean! ?
