I mean, hell, I feel like I've been "a wife" for plenty of men I've simply lived with as housemates tbh.

It's taken for granted that guys can expect their female housemates to provide a listening ear...someone to do the dishes when they can't, or won't, or get too busy, or simply don't feel like it...someone to be a verbal/emotional punching bag...someone to be eye candy and look cute so they can flirt just a bit, but it's all safe and socially acceptable, even when they already have girlfriends. Really. It's the most bizarre thing.

I'm never going to live with a man ever again unless I'm married to him, and even then I'm never going to be a "wife" unless he's willing to be a "wife" right back!
