What Makes You Say I Love You To Me?

what is it that makes you think you love me?
what do I do that makes you so happy?
you say you love me
but you never really told me what exactly it is that makes you think you do see?
I believe you but I'd like to know why
do I make you smile and sigh?
your not a book, I cannot read you
but I swear I try my best but I haven't yet and that is true
I want to know why you think your in love with me
since your feelings I can't see
what is that makes you feel that way?
surely there are some words you could say
