Sample Apology Letter for Cheating on your Girlfriend
I know you are really mad at me and you have all the right to be. I am extremely sorry for what happened. I know infidelity is just not acceptable to anyone in a relationship and it is surely the most harmful thing in any association but all that I did, it just happened because of the situational factors. I never meant to cheat on you, I can never even dream of it. You know that I love you from the bottom of my heart and you mean the world to me. It was just one mistake that I made and that too because I was not in my senses.
My love, I cannot undo the things that I did in past but I promise that I will never ever do anything that will hurt you. I have had a lesson for life and cheating on you for one moment made my life hell. You seem so far because you are so upset. I cannot see you in such a bad shape and therefore, I am writing this apology letter to you because I am very sorry. I am repenting for things I did which I should not have. But please trust me, for every word that I have said is true. I love you the most and that is the end of world to me. I did a mistake and I am sorry for that. I can only promise that it will never happen again.
If you want then I can explain you in detail what happened that day and then things will become clear to you. But please give me one last chance to set things right, to tell you that how much you mean to me and I cannot afford to lose you.
Looking forward for your call.
