Sad and Confused

What did I do?
I screwed things up,
Now I'm confused,

I knew it from the start,
But I didn't listen to my heart,
I wanted to believe,
That you wouldn't play with me,

Now its all a matter of waiting,
That's all I ever do,
Don't know if you'll call,
Or find someone knew,

I feel like an idiot,
An utter fool,
For letting myself,
Fall in love with you,

I'm tired of your game,
It's driving me insane,
By the day my heart crushes,
Dragging down my hope,

I should just let go,
Move on,
But there's always that if,
That won't leave me alone.
