I feel with apologies that a display of empathy needs to come out.
"I can see how (stated behavior) can cause (stated emotion). I'm so sorry for doing this, because I don't like feeling that way myself. I need to address this about myself. I hope in time to become mindful about my behaviors. And I hope in time you'll notice this change and can find forgiveness of me. I'm sorry for hurting you and creating this rift. I value our friendship and can understand if you need space from me."
