Can you pass the compatibility test?

There are some pretty well-established relationship qualities that confirm you and your new partner are a match made in heaven: excellent communication, a feeling of giddiness and delight when you are together, a sense of ease and comfort. But what are the weirdest signs you’re compatible? At first sight, they might make you stop and scratch your head and say, “Hmm … really?” But after you stop and consider it for a little while, they actually start to make sense, even though they are certainly not normal conventions of what stellar relationships look like. It’s the wild and wacky stuff that just makes you good together, even though it maybe doesn’t completely make sense. That kind of stuff.

I reached out to dating and relationship experts to find out what kinds of things they’d nominate for this list, because all I could think of was a mutual love of Seinfeld, When Harry Met Sally, and long meals in bed. (Best match ever!) Here are 12 ways you can tell if you’re compatible with your partner that you’ve never thought of before. Take that, haters who secretly thought you’d never find the perfect, head-over-heels, drunk-in-love match of the gods!

1. You’re The Same Kind Of Shopper

Nope, didn’t see that one coming. “If you’re both bargain hunters, you’re more likely to be compatible than if one of you is a spender and the other a saver,” New-York–based relationship expert and author April Masini tells Bustle. Ohh. Yeah, that sounds about right.

“Money is a big deal in relationships, and shopping is a daily or weekly event, whether it’s just buying gas for the car, or food shopping, clothing shopping, shopping for a new car, a new condo or new furniture. When you have similar shopping habits, you’re less likely to fight over money and more likely to have an easier time together in a relationship.” So spendthrift + spendthrift = love, and miser + miser = love, but as for spendthrift + miser, well, ne’er the two shall meet. Got it.

2. Your Mutual Friends On Facebook Are Blowing Up

Do you have, like, 100 mutual buddies on FB? A lot of friends in common is a sign of mutual compatibility, life coach Kali Rogers tells Bustle. “Before online dating hit the internet, the majority of couples met through mutual friends,” she says “If you share a lot of the same network, chances are you share similar tastes and values, considering you hang out with a lot of the same people.” And this could lead to a happy, healthy relationship. Plus, you already know lots of each other’s friends, so you already have that part down pat. Easy-peasy.
