Im done worrying

To the guy who broke my heart
Im kinda glad we fell apart
I say you used me and you know for what
And then it was just like bit*h your cut
Cut outta your life just like that
You threw me out like an old doormat
I dont know why it still bothers me
I thought by now i would see
See that you were just a user
Someone who once said id be a loser
Well newsflash i will never be one
And from here on out i am so done
Done caring about how you used me
Cause theres someone out there thats better you'll see
So stop hating on me and what i do not that you have a clue
Just worry about the next girl you wanna go do
Hopefully she will see through you and get away
I should have done that the first day!
