Apology Letters to Romantic Partner.
Responding to Ex Causing Hurt

I’m really sorry for how my response to my ex affected you. I didn't think it through, and I see now how my actions hurt you deeply. You didn’t deserve to feel that pain, especially when you’ve always been so trusting and supportive of me. I understand that by engaging with her, I crossed a line that made you feel insecure and disrespected. It was thoughtless of me, and I take full responsibility for that. I never wanted to cause you any tears or make you doubt what we have. You mean the world to me, and I hate that I put you through this. Moving forward, I promise to be more mindful of how my interactions can affect you and our relationship. I will set clearer boundaries and prioritize our connection over anything from my past. I want you to feel safe and secure with me, and I know I need to earn back your trust. Please take the time you need to process this. I’m here whenever you’re ready to talk, and I hope we can work through this together. Your feelings are important to me, and I want to make things right.
