Second Best

I don't know why I feel this way
I'm actually getting scared
I hate that I am jealous
even though I shouldn't care
I want her to be happy
even though it will be with you
I'm not sure if i can take this
Ive already been put through
you dating someone else
me being left behind
I hate your guts I do
but you're always on my mind
I have to let you two be
I know it in my heart
but I want so much to break you up
and I know that that's not smart
I want you to be happy
with anyone I guess
its just painful to know
I was only second best..
