Why?

Just wanting to be happy,
Is that too much to ask?
All you do is criticize,
On each and every task.

You're never satisfied,
No matter what I do,
I try and try my hardest,
Still not good enough for you.

I'm sorry I'm not perfect,
As much as I try to be,
I can't deal with this much longer,
It's just way too much for me.

Now, as soon as you're not here,
I'm gone without a trace,
I need to get away,
I need to leave this place.

I'll find someone better,
Someone who treats me right,
Someone who doesn't fight with me,
Before I sleep at night.

Someone who makes me happy,
And is happy for me too,
Someone who likes me for me,
Someone who isn't you.
