Apology Letters to Girlfriend.
Hurting You By My Thoughtless Mistake

I'm so sorry I hurt you by my mistake — by not listening to you and then saying things that were cruel and dismissive. I know I made you feel small and alone when you needed me to be steady, and that breaks my heart. This was entirely my fault. I should have paused instead of lashing out, I should have heard what you were trying to tell me instead of reacting. I can't take back the words I said or the way I made you feel, but I can own them and learn from them. I understand that my behavior damaged your trust and made you doubt whether I truly have your back. I understand that you felt dismissed and hurt, and that means I failed you as a partner. I am genuinely sorry for causing you pain. To make this right, I will practice pausing and listening before I speak, I will check in when I feel triggered instead of blaming you, and I’ll work with a counselor to deal with the patterns that lead me to act this way. I want to show you through consistent actions that I’m changing, not just saying the words. Take whatever time and space you need; I respect that. When you’re ready, I want to listen — fully — to how this felt for you and what I can do to rebuild trust. I love you and I want to do better for us.
