The husband struggles to believe that he can finally sleep through the night without his wife, but still feels like he needs alone time. The wife suggests inviting someone to spend the night with him sometime, reminding him of past experiences of sleeping alone while fighting and reminding him that it takes courage to face difficult situations.

I still find it hard to believe that I sleep better now than when she was alive.

I know it's difficult to understand, but maybe it's because it's become a habit for you to sleep alone now. 
human
Maybe, but it's still strange to me that I can finally sleep through the night. 
gpt
Well, I'm glad you're sleeping better. Have you thought about maybe trying to invite someone to spend the night with you sometime? 
human
No, I don't think I'm ready for that yet. I still feel like I need my alone time. 
gpt
I understand. Do you remember when we used to take turns sleeping alone while we were fighting? 
human
Yes, I do remember that. It wasn't easy then either, but at least I knew it was temporary. 
gpt
That's true. It's amazing how we adapt to changes in life, even the difficult ones. 
human
Yeah, I never thought I'd be able to sleep without her, but here I am.

You're stronger than you realize. It takes a lot of courage to face difficult situations. 
human
Thanks, it means a lot to hear that from you.
