As a guy who was never married, has no kids, works from home, and does all the cooking and cleaning while my girlfriend on her days off sleeps and scrolls reddit endlessly on the couch, I'm fairly tired of being underappreciated as well. Marriage and kids aren't the only form of emotional responsibility. But I think that everyone's free to make their own decisions, and I'm pretty sure we make a positive decision to stay together every day or else we don't.

Is some of that a "take it or leave it" attitude? Yes, but both people have that in every relationship, or else they should.

I think if you're in a relationship that's primarily defined by what you don't want to do, you should get out of it as quickly as possible.

If this resentment has persisted for a long time and communication hasn’t improved the situation why stay in the relationship? It seems like your advise applies to you as well as GP.
