Another important factor in love compatibility that’s often overlooked is personality type. What is a Type A vs. Type B personality, and how do these types of personalities affect relationships? The concept arises from the Type A and Type B personality hypotheses, originally developed in the 1950s by cardiologists Meyer Friedman and Ray Rosenman. In later years, further research and controversy surrounding the funding of early studies by tobacco industry giants Philip Morris (now Altria) and RJ Reynolds led their work to be largely discredited in relation to coronary heart disease, However, this theory still provides useful insight into our mental states and psychology.

Why do personality types matter in relationships?

When you’re in the early phases of love, also known as the honeymoon phase, it’s easy to overlook things about your partner that might bother you down the road. Understanding all the parts of what makes you will help bring clarity and understanding to situations when the rush of new love hormones starts wearing off. If you become triggered by something your new love said or did, knowing your personality type is a tool you can turn to understand why. This can also help you know more about your own core values and prioritize your “must haves” when looking for a long-term partner.

Your personality type helps define your needs in a relationship.

Once you’ve determined if you are a Type A or Type B, here’s how to create your buckets. Take a piece of paper and draw a line in the center. On the top left side write your “Must Have” and on top of the left column write “I’m ok without It." Fill out the columns with items that are really super important to you.

How do Type A and B personality types affect romantic compatibility?

You may wonder If it’s better to match up with a partner who has the same type of personality as you, or if this is a case in which opposites attract. Here are a few guidelines to consider based on the possible variations.

If you’re a Type A personality dating a Type B:

Type A’s often have high expectations of themselves, but they don’t always need their partner to have those same expectations. On the contrary, it can be quite relaxing for a Type A personality to be influenced by a Type B. It’s almost like a mini vacation of the mind when you are together with this other person. You can compliment each other, as a good balance of opposite types can make a relationship thrive. On the other hand, Type A personality types might find Type B’s laid-back views and relaxed approach to life so frustrating they won’t be able to tolerate dealing with those personality traits in their life for long.

If you’re a Type B personality dating a Type A:

On one hand, it can be quite stimulating to connect with a Type A personality. You may like being challenged to learn new things, and they may expand your horizons. On the other hand, it can be quite overwhelming. You may end up feeling like you’re always being pushed over your limits, and not in a good way.

If you’re dating someone with the same type of personality as you:

Sometimes, the things that bring conflict in a relationship have to do with whether or not you share the same values as your partner, like cleanliness or levels of ambition. Choosing a partner with the same personality type might prevent some of the types of arguments and conflicts that arise between people who have different ways of viewing and behaving in the world. The beauty with all of this is that you get to choose! Ultimately, love is love. There is no right or wrong answer. Love and relationships get complicated no matter what. But when it comes to choosing a partner and navigating the emotional waters of all that relationships entail, it’s always good to have some helpful tools in your pocket.
