Specialist at losing

Your loss, I say,
but why I'm the one losing
my heart without you.

Your loss, I think,
I hate you for coming
into my life,
I hate me for letting
you in.

Your loss that you didn't
care for me
so that I could give
you my best.

Your loss am I
even though
I wasn't yours to lose.
But a specialist at losing
(such as you)
can lose anything!
