Winner Takes None

I want to win, but the problem is,
You want to win too.
Well, it's not much of a problem for you.
There was a time when I could win,
And you would lose.
However, I ended up losing,
And you ended up winning.
It hurt my ego, real bad,
And I swore I would never let you win again.
Now it has come to a point where,
If I win, you win too.
But I don't want you to win, 
And I am tempted to embrace defeat, to see you lose.
How can I get what I want,
And not give you what you want?
I hate it that we both want the same thing,
But it was I who changed, so why blame you?
Actually, why does it bother me so much if you win?
Go ahead, knock yourself out,
And while you're at it,
I might win.
