When you think of modern dating, you don't usually think of 1,225 page novels by bearded Russian writers who spent their free time looking like this:\n\tAdvertisement - Continue Reading Below\n\t\n\nBut before Sex and the City was shedding light on the complications of coupling up, Tolstoy was over in Russia penning the 19th-century version of a cable TV drama. Anyone who's been watching the Lifetime miniseries knows War & Peace is basically a soap opera starring men in furry hats who woo women in similarly furry hats, while illustrating some valuable (and surprisingly contemporary) dating lessons. Including but not limited to: when given the chance to make\u00a0out in the snow, take it.\u00a01. He's just not that into you.\u00a0If War & Peace has taught us one thing, it's that we should have an equal-opportunity disdain\u00a0for both\u00a0the player\u00a0and\u00a0the game. Poor Sonya Rostova (played by Aisling Loftus)\u00a0is\u00a0learning this lesson the hard way thanks to her unyielding crush on\u00a0her cousin, Count Nikolai (Jack Lowden)\u2014a man who openly flirts with other women and once\u00a0told her, "I've fallen in love before and I expect I will again." Uh, romantic? To be fair, it was cute when Nikolai went against his parents wishes and proposed, but still: if your boyfriend says he's into other women, time to move on. Also, maybe don't date your cousin.2. Long distance relationships = the actual worst.Due to #ThePatriarchy, the women of War & Peace tend to spend their time at home while their boyfriends gallantly fight in hilariously large hats. This means almost all the primary relationships are long distance, and most are strained at the best of times. Take\u00a0Sonya again: she spent months pining for Nikolai when she could have been out living life and perfecting whatever the 19th-century version of an OK Cupid profile is. Lesson learned: don't wait for your date.\u00a0\n\tAdvertisement - Continue Reading Below\n\t\n\n3. Your first love *probably* won't be your last love.When the characters in War & Peace fall, they fall hard. Hard\u2014like "let's get married even though the only thing we have in common is the ability to eye-sex on the dance floor" hard. Relationships lacking a strong foundation tend to burn out, a fact Natasha learns when she falls for\u00a0Prince Andrei\u00a0and then is like, "meh, forget it, I wanna live in the woods" once he peaces off to Europe.4. A\u00a0sexless relationship is reason to bounce.War & Peace's lovably earnest\u00a0protagonist, Pierre (Paul Dano), might be Uncle Scrooge-ing it when it comes to wealth, but his wife (Tuppence Middleton)\u00a0has no\u00a0sexual interest in him whatsoever,\u00a0and their relationship suffers because of it. Yes, Princess Helene's sole purpose is to make Pierre miserable, but there's something deeper to be said here. Sex is a normal part of healthy relationships, and if you're not having it, it might be time to \ud83d\udc4b\ud83d\udc4b\u00a0\ud83d\udc4b.5. Your best guy friend will inevitably announce his love for you.Oh, you thought you and your roommate were best buddies who would never cross that invisible line? Nope, s/he's been pining for you this entire time. Case\u00a0in point, this conversation between\u00a0family friends\u00a0Denisov and Countess Natasha:Denisov: "I think about you all day, dream of you at night."Natasha: "Oh dear."Nailed it.6. We're all ostensibly maintaining constant illusion of max chill.Much like the rest of us, couples in old-school Russia\u00a0spent their time\u00a0scrolling through their texts and obsessively checking Instagram. By which we mean\u00a0staring vacantly out the window waiting for carriages and/or\u00a0trolling the mailman. The\u00a0complete absence of chill is all too familiar,\u00a0which is ironic given how cold winters are there.\u00a07. Don't sleep with your best friend's girlfriend/boyfriend.Fact: Dolokhov literally cannot stop flirting with (and in Helene's case, sleeping with) his friends' wives/girlfriends. This is a\u00a0terrible idea no matter what century you're inhabiting, and one that landed Dolokhov in a shoot-out. This guy was literally almost murdered\u00a0for sleeping with Pierre's wife,\u00a0and he still went and proposed to\u00a0Nikolai's girlfriend.\u00a0If your best friend sleeps with your boyfriend, however, challenge them to a casual duel.\u00a0Kidding, don't do that. But you could challenge them to a pizza eating battle, because then everyone wins.Follow\u00a0Marie Claire on Instagram\u00a0for the latest celeb news, pretty pics, funny stuff, and an insider POV.
