your not in love with him your infatuated. that's not a bad thing. maybe it's good that you experience this so you will know the difference when you grow up.
you cant tell someone guy you dont know that you love him. being at that young age, he could tease you to his friends.
i've always been a women who felt as though the guy should be the one that approaches the women.
from your other post, i assume that this is the guy that you think about having sex with.
