I was thinking about how there can be ISFJ-ISFJ or INTJ-INTP or other similar type relationships, and how that works for some people, but other people have more success with a partner of a somewhat different type. So here is my line of reasoning regarding that.
There are some aspects of each personality type that probably could be viewed as "weaknesses" or areas of growth towards a more balanced individual, or at least necessary to relate to people who are different (type-wise) from you. In romance, seems to me like people who are either naturally more balanced in type preferences or who have worked on these areas of growth in themselves, often are more successful in relationships with people who are different from them.
But people who do not see these traits or mindsets as areas of growth - maybe even see this as the best way of experiencing the world, or way that makes the most sense - are more successful in a relationship with someone of a more similar type to them.
What do you think? Are you more successful with someone more similar or more different from you (in terms of MBTI types)? What factors contribute to that?
Of course there are soooo many aspects of compatibility: interests, values, beliefs, etc. Just talking about MBTI here.
