I still can't believe you cheated on me. How could you do that to me?
gpt
I know I made a terrible mistake, and I'm so sorry for hurting you.
human
Sorry doesn't even begin to cover it. I thought we had a strong and loyal relationship.
gpt
We did, and I don't know why I did what I did. I was in a bad place emotionally and I made a terrible decision.
human
That's not an excuse. You knew how important loyalty and trust are to me.
gpt
I know, and I want to do everything I can to earn back your trust.
human
It's not going to be easy. I don't even know if I can forgive you.
gpt
I understand that. I just hope that one day you can find it in your heart to forgive me.
human
Maybe. But for now, I need some time to think about everything. 
gpt
I understand. I'll do whatever it takes to make things right between us.
