I think that Gabby is trying to make her husband see that her exploration really has nothing to do with him and he isn't deficient (well, except for a few things). Just like someone else mentioned, it is exactly like Frankie and Gracie where because the cheating/dumping are for a men vs say, younger women, it's more like a deep need she can't ignore anymore. Not sure how less of a sting it is for Mr. Curly to go after a guy vs a younger woman. Both would suck.
Speaking of which, Mr. Curly watched half the episode with me and LOVED it. He hates all teen shows but did go to school with Jennie. I think he liked seeing her play herself.
Nate vs Brian. It is gender biased but I think there is a sense that when a family is having financial problems, all members (especially the man) should try and fix that. He didn't seem thrilled to watch the kids or work. Brian seems to have a relationship where his contribution is child rearing and the home.
Is his wife on the same level of Beyoncé where everyone freaks out and would only want to ask questions about her?
