the feeling was blight in the midnight air
an awful fright, as I looked at my hand
sentenced to linger, a burden to bear
still on my finger; your gold wedding band
tonight is the night, I know it’s not fair
this horrible plight, I don’t understand
so now we are here, at a table for two
I swallowed my fear, my darling we’re through
I caught her with you, alone in my bed
you were so untrue when you betrayed me
I picked up the gun and I shot her dead
so now it is done and I’ll make you see
I’ll treat you like her, I filled her with lead
or do you prefer I let you go free?
you see how we are, you think all is fine
enjoy your cigar, I poisoned your wine
Adding your comment:
Superb rhyming and meter kept it flowing like that hot lead that the biatch got filled with. 
All I could think at the time was, serves her right, you don't mess with someone else's man. 
...Good for you...Cheaters never win! they sometimes get shot
