1. Wow, that was not okay of me. I know I can't undo what I said, but I want to acknowledge that I regret it and I'm so sorry for letting my temper get the best of me. That was unfair to you.
2. The way I said that wasn't fair or appropriate. I'd like to try again and express what I was feeling in a more productive way—are you open to hearing it?
3. I just messed up. I used my words as a distraction from the real issue, and I'm so sorry for hurting you. How can I make it right?
4. I didn't mean what I just said. I'm really disappointed in myself for reacting before thinking about how hurtful those words were. I need to take a breather to collect myself and be more respectful. I'm so sorry—can we come back to this in a few minutes?
5. You didn't deserve that. I was speaking from a place of raw reaction instead of thoughtfulness and intention. Are you okay? I'd like to take it back and say something different if you're willing to hear me out.
