I would like to get as many inputs as possible from you guys.
Socionics states that duality is the most rewarding relationship because it satisfies both partners' needs for completeness. Stages in this relationship also vary from being shaky to unbreakable (ONLY if there are mutual attractions and both partners have the same goals in life). I've met some ESTJs throughout my life, but they just don't seem to notice my presence (the introvert dual is supposed to fade in the background).
Regarding the ENFP: I LOVE ENFPs. I adore ENFPs. It's been my dream to end up with one, be it friendship or family life. I wish there could be more. But the 2 ENFPs that I met seemed very....distant. I even showed them my sincere intention to be friends. But oh well, maybe other ENFPs can explain about this, not just for romantic relationships but friendships as well.
I can still see how loving ENFPs are. They think far ahead and use feelings when making decisions, which can be seen as irrational. However, those are what make them dedicated to their relationships.
Your comments are appreciated. Thanks!
