I need to learn more about this Enneagram stuff. I’ll put it on my list. It sounds like 4s and 7s are about as ying and yang as you can get on this scale. Maybe that explains some of the problems in your R? The more opposite you two are, I would guess the higher the potential for enmeshment, and therefore the harder to differentiate, the bigger “push” needed to get you and your partner to move off center and start to evolve. I need to take that Enneagram test and find out where my wife and I fall.
Does it stand to reason that once you start to evolve and become more functional, the more polar opposite the partners are, the stronger the eventual relationship can be?
