How does one decide?

One heart
To share the love I feel
With two people
I am at gods will
The one I live with
Day to day
Always took
My breath away
The love I thought
Had long gone
Comes rushing back
His great charm
Two people
Steal
This great heart of mine
One person though
Is all I can have
Decision that I cannot make
The love I have known
Or the love I always wanted
How does one's heart decide
Between the two
The great divide
To stay right where I am
And lose that which I desired
Or to go with he who made
In my chest burn eternal fire
This great dilemma
Ever grows
So very deep inside me
How does one choose
Between your hearts desires
