It was really hard for me to leave you, but it was the right thing to do.
gpt
I still can't believe you actually followed through with it. I thought we could work things out.
human
We tried for so long and nothing seemed to improve. Our relationship was toxic and I couldn't keep living that way.
gpt
I know I made mistakes too, but I was willing to change. You didn't even give me a chance.
human
I did give you chances, but the same issues kept arising. I can't keep going in circles.
gpt
You're just going to give up on us like that? After everything we've been through?
human
It wasn't an easy decision, but it was necessary for my well-being and mental health. I hope you can understand that.
gpt
I do understand, but it doesn't make it any easier for me. I thought we had a future together.
human
We may still have a future, but right now we both need to focus on ourselves and figure out what we truly want. 
gpt
I just wish you could have communicated better with me before it reached this point.
human
I understand that, and I'm sorry for any pain I caused. But we need to accept the situation and move forward.
