What are some tips for an introvert-extrovert relationship?

Maturity: You’re both going to need it, seeing as how you get your energy recharged/depleted in different ways (the introvert via solitude/engagement with people; the extrovert via engagement with people/solitude—the exact opposites of each other). That means a lot of the time you’ll be getting your personality wants satisfied (1) via others {for the extrovert} or (2) by yourself {for the introvert}. In a romantic/sexual introvert-extrovert relationship, it will require a lot of maturity on everyone’s part not to let jealousy and insecurity creep in. And no, this is not an excuse to (1) pressure an unwilling partner into an open relationship or (2) condone cheating . That’s a different and unrelated set of desires and decisions that doesn’t necessarily apply to personalities.  If you’re not exactly sure what your personality type is, be willing to take an MBTI personality test.  Many people actually fall right in the middle of that scale (ambiverts).

Flexibility: You’re going to occasionally want to challenge yourselves to try to understand the other person on their terms. That means sometimes stepping outside of your comfort zones, but never to the point of discomfort. Be willing to negotiate when and where you do this.

Privilege: Although it seems like the introvert/extrovert relationship can exist on a 50/50 footing, that’s only in an ideal world. The truth is there’s massive bias toward and pathologizing of introversion. That means the extrovert will be the unwitting recipient of societal privilege. (“What’s wrong with your partner/friend?” “They seem cold and unfriendly.”) The extrovert can alleviate this to a great degree by defending the relationship against such bias. (“There’s nothing wrong with them. That’s just their personality. They get their energy needs met in a different way than I do. Plus, their energy depletes with too much social interaction. Regardless, come say ‘hi’ to them.”)

Good luck and congratulations.
