Couples therapist Lori Gottlieb is quoted in "How to Be Married" saying that you shouldn't expect to split household tasks 50 50 with your partner.

Gottlieb suggests that the division of labor should be more organic, so that each person feels fulfilled.

That may be harder than it seems. Even today, women still tend to bear the brunt of housework.

One strategy is to get clear about who's doing what around the house, and then swap or outsource tasks so that each person winds up happy with their responsibilities.

There's a scene in one of my favorite movies where the viewer learns that a woman and her husband split all their expenditures precisely 50 50.

Except what's really going on is that the woman is paying for half of things that only her husband uses — she's even paying for half of the cat's flea treatment, even though the cat was a gift from her husband.See the rest of the story at Business InsiderNOW WATCH: The key to long-lasting relationships is more simple than you thinkSee Also:Having kids can turn every relationship issue into a fight and renovating a home might be just as badThe relationship history of Elon Musk, who says he must be in love to be happyGisele Bundchen's actions after Tom Brady lost the Super Bowl hold an important lesson about how to treat your partnerSEE ALSO: Making a simple list with your partner can save your relationship and leave you a lot less stressed
