I'm writing this letter because I need you to know how deeply sorry I am. Words on a screen can't fully express the weight of my regret, but I hope this message reaches your heart.

I made a mistake that hurt someone I care about deeply - you. There's no excuse for my behavior, and I take complete responsibility for my actions. Looking back, I see how wrong I was, and I wish I could turn back time.

You've shown me kindness, trust, and friendship, and I betrayed that. I understand if you need time, and I respect whatever decision you make about us.

But please know this: I am truly, genuinely sorry. I will work hard to earn back your trust if you'll give me that chance. You deserve better, and I promise to be better.
