I'm Not A fool

I ain't no fool and I don't take what I don't want
I don't wanna say that I've been unhappy with you
But as from today, well I've seen somebody that's new.
I wish nothing but the best for you, too,
Don't forget me, I beg,
I remember you said,
"Sometimes it lasts in love,
But sometimes it hurts instead,"
Through thick and thin you will always be my friend.
