Not sure if the person you’re dating is the one? Take a trip to IKEA.

The Swedish megastore is getting called out by a clinical psychologist for what most frequent visitors already know: happy couples who walk into an IKEA often walk out fighting.

“The store literally becomes a map of a relationship nightmare,” psychologist Ramani Durvasula told The Wall Street Journal. Strolling through the store's showroom, which is filled with staged kitchens, nurseries and more, can apparently bring touchy topics to light, such as who actually cooks, cleans, cares for kids and more. And the complex task of actually assembling the furniture opens up an entirely different can of worms, filled with short tempers, outbursts and frustration.

With 367 stores dotting the globe, the store's low prices often attract young couples starting to furnish a home, thus making it a perfect place to put a budding relationship to the test. Strolling through the marketplace can be an exciting adventure of piecing your lives together. But for some couples, the maze of a floorplan is the end of the road, as hilariously demonstrated by Tina Fey and James Marsden’s characters in “30 Rock.”

Our advice: If you’ve made it through the store and put together the tricky Hemnes dresser without blowing your gasket at your significant other, you’re a match made in heaven.
