Who do I choose?

A simple Tiger, fought over by two.
A stubborn bull,
And an Eagle who soars true.

She must choose one,
But to one, her heart belongs,
The other all alone.

The Tiger shared much history with one,
Yet the other is a mystery to her eyes.

One of regal birth,
The other is not,
Though both are special in my heart.

If my love leaves,
I shall break,
Never to return.
