What did i ever do?

I don't no what went wrong,
But something wasn't rite..
I love you, and you love me
But all we do is fight..
The old days were so fun..
You had so much to give,
Now were all upset
I don't even want to live..
You were what I ever wanted
You gave the world to me
You don't think I gave it back
I don't know how you couldn't see
See that all I did for you
I showed you that I cared
theres no way id ever cheat on you
I knew it wouldn't be fair
Just want you to no, Ive never felt like this
Hurt so much at all
Thought you were mine forever
But promises always fall...
