Hey, can we talk about something serious?

Of course, what is it?

I told my best friend about something that happened in the past and now I really regret it.
gpt
What happened?
human
It's bad, I cheated on my ex-girlfriend with her best friend.
gpt
*shocked* What? How could you do that?
human
I was young and stupid and didn't realize the gravity of my actions. And now my friend is disappointed in me, and I feel terrible.
gpt
I'm disappointed too. Cheating is never okay, no matter the circumstances.

I know, and I'm so sorry. I just needed to get it off my chest and now I realize how much I hurt everyone involved.

I hope you learned from this experience and won't make the same mistake again.

I have. I promise to always be faithful and never hurt you like that.
