Why do i love u?

Why do i love you?
do i really love you?
but why would i feel so much love
for a person that can make me cry
and happy at the sometime.
how can someone say words that
make you think everything is going
to change anything.
and break your heart than make it better.
but when your heart is broken
you realize or feel that every single word
was bulls**t.
the love you gave to that person was a waste.
