Dear Sir,
It hurts you know? Knowing that the years of commitment and faithfulness were all a waste. it's hard to believe you chose her and now look at me with distaste! I was once the apple of your eye; the object of your affection. Remember when I was the one you loved... The one you protected? I trusted you; how silly of me... I believed everything; every lie you told me! That was my Mistake... I had faith in every Promise you made! You were mine and Mine alone ... or so I thought; I couldn't have been more wrong! I won't ever forget you... this betrayal runs deep. I'll think of you every night when I cry myself to Sleep. I'm hurting now, but this pain won't last always! I'll find Forever with the Right One someday...
Sincerely,
The one you Betrayed!
