I bought you a vanilla-scented candle, my love. 
gpt
Oh, it smells so good. Thank you.
human
I love doing little things like that to make you happy.
gpt
You always do. I'm lucky to have you.
human
I'm the lucky one. You make every day brighter.

Speaking of making days brighter, remember when you gave that hot meal to the homeless person a few weeks ago? That was such a kind gesture.
human
I know, it's important to do what we can to help those less fortunate.
gpt
Exactly. And it shows what a big heart you have.
human
On the other hand, do you remember when I caught you cheating on me with another woman a few months ago?

*silence*

I'm sorry to bring it up again, but I just want to know why you did it.
gpt
*still silent*
human
It hurt me deeply, and we need to talk about it if we want to move forward.
gpt
*tearfully* I don't know why I did it. I was lost and confused.

We can work through this together. But right now, let's focus on the present and how much I love you.
gpt
*smiling through her tears* I love you too. And I appreciate your patience and kindness more than you know.
human
*smiling back* I'll always be here for you, my love. And now, let's finish those dishes before mom gets home.
