Writing/editing groups are really helpful for plotting your story, checking to make sure you haven't used "very" very often and catching errors like the metaphor "wobbly as a three-legged table." (Three legged tables actually don't wobble.)
But when you're mid-paragraph and have a crucial character question (especially considering the character in question is Our Hero), it is particularly helpful to have a husband with no sentiment regarding your plot.
For example, writing from Our Hero's point of view, the thought crossed my mind that when he noticed that Our Heroine's dark hair was similar to his own, he would think what lovely dark-haired babies they would have. I started to type this but stopped...something didn't feel write. Sure enough, when I consulted with the hubs, he laughed aloud. "Men never think things like that. He's probably just looking at her chest wondering how to get her in bed."
Sigh...I didn't write the bit about the dark-haired babies.
Great, all I need is one more reason to procrastinate! As if Instagram wasn't enough...
