Maybe 

Maybe I don't understand other people's feelings. Maybe I don't care. If I try to love everyone at once, I'm hurting someone else I know I should feel is important to me. 

This is to the one I love:

It is eyes that I look at first to decide
whether or not my cruelty should be justified.
If reasoning doubts such a thing called open love 
My heart only belongs to one. 

Will honesty in my mind let me keep this to myself as it is true to my heart?
No, unfortunately not. 
But if reasoning doubts such a thing as open love
My cruelty is surely justified 
as my own values tell me that my heart only belongs to one.

On impulse or feeling can I say that my love wanders so curiously?
That in practiced restraint does my faith still belong to one
What is my virtue, means nothing.
Unless my virtue means loyalty.

It does still remain in the eyes of who I love 
That his love for me is true. 
And for those whose eyes gaze into mine to see nothing
My cruelty is surely justified.
With reasoning, my mind denies what my heart accepts

My heart accepts love from all
But my love belongs only to one
Even if my cruelty is justified
It is what I see in your eyes that my love is what I decide.
