Changeling

Pretty much nothing that you say or do
Can change how I will feel about you now.
Of course in say that I must allow
For mighty alterations coming through,
But in the realm of everday, I see
No chance that you will change the way I think,
For I am nowhere even near the brink
Of alteration, or inconstancy.
A murder, or of course adultery,
Sins unimagined even in the stink
Of deep damnation, by those souls who sink
Into their own destruction willingly
Might change my mind: but otherwise, I'm set:
Your goodness is too mighty to forget.
