This Is What People Get Wrong About Compatibility, From A Marriage Therapist

Whether you're an astrology girlie who knows exactly which signs you're compatible with and which to avoid, or you're just that person absent-mindedly taking internet quizzes to see if you and George Clooney would make a great couple (guilty), compatibility is a buzzy topic these days.

While the word gets thrown around pretty loosely, compatibility in relationships generally refers to how well two people's personalities, lifestyles, beliefs, and other characteristics align and can yield a functional, healthy relationship.

People can sometimes confuse compatibility with similarity. They look for similarities in personality, lifestyle, political beliefs, and other such factors to determine whether they're compatible with a potential romantic partner.

But according to licensed marriage therapist Racine Henry, Ph.D., LMFT, having these areas in common doesn't guarantee compatibility—or harmony, for that matter.

"Personally, I don't believe a couple has to agree on anything," she recently told mbg. "These can be starting points for a bond or help establish those initial feelings of interest, but when there's tension or a lack of positivity, being from the same hometown won't matter."

There are times when differences can cause tensions in a relationship—for example, if you love spending your downtime as a couple while your partner generally likes a lot of solo time, or if you love weekends in and they love weekends out. These issues can be worked through, but you might have an easier time in relationships where you were naturally aligned in these areas. As well, having different political beliefs or religions (as another example) truly is a deal-breaker for some people.

"Compatibility is a natural, effortless way of relating to another person and feeling a connection," Henry explains. "It can also be the ability to work together well and compromise around tough issues."

That piece about compromise is key. The truth is, no two people are going to be perfectly aligned in every single part of their life, and every couple will encounter areas of disagreement eventually. What matters most is how they're able to move through those disagreements and how well they're able to accommodate each other's unique qualities and needs.

"You have to be able to compromise repeatedly and have a mechanism for solving problems," Henry says.

While compatibility does matter when it comes to finding a solid relationship, it's important to recognize that compatibility means more than just being really similar to each other. Having certain things in common can add a lot of ease and joy to a relationship, but every couple will still need to be able to accept each other's quirks and be able to work through the inevitable areas of conflict.
