The husband wants a divorce because he can't pretend to care about anyone other than himself. He wants to live his life the way he wants to live it together, but the wife is still upset and wants to move on separately.
human
I've made my decision, I want a divorce.
gpt
What?! Why do you want a divorce?
human
It's clear that we can't make this marriage work. I always put myself first and I don't care about your feelings.
gpt
That's not true, you know I care about you too. Why can't we work this out together?
human
Because I can't keep pretending that I care about anyone other than myself. I don't want to be in a marriage where I'm not happy.
gpt
But what about me, and our vows?
human
The marriage vows were made by the person I used to be, not the person I am now. I want out.
gpt
I can't believe this is happening. What about our future plans and the life we wanted to build together?
human
I can't fake it anymore. I have to live my life the way that makes me happy.
gpt
I still don't understand why you have to leave me. You're being selfish.
human
I know I am, but that's just who I am. It's better for both of us if we move on separately. Let's just try to make this as painless as possible.

Fine, but I hope you can find happiness in your selfishness.
