The husband blames his math test failure on feeling like he's not good enough. The wife reminds him that one setback doesn't define his abilities, reminding him that his abilities are more than good enough.

I just can't believe I failed that math test. I've always been good at math.

Babe, everyone has bad days. Plus, one test doesn't define your abilities. 
human
I know, but it just feels like I'm not good enough. 
gpt
You're more than good enough. You're smart and hardworking. Don't let one set back define you. 
human
It's just hard. I've always prided myself on being a good student. 
gpt
I understand. But remember when you talked about how you knew I was the one when you met me? That same intuition applies to your abilities. You know you're smart and capable, despite this one setback. 
human
You're right. Thanks for being my support system, always.

Of course, babe. That's what partners are for. We're in this together.
