Dual relations are supposed to create comfort for you as it is a totally supportive relationship. But then the more comfortable one is, the less one has a sense of being "alive". I've been told of dual relations that have broken down. From my reading, when you are with your dual you lose your awareness of them, I think because you fit each other perfectly.
One person told be the relationship became boring (INTj-ESFj). Another said that they were interested in ideas and their dual was not (another INTj-ESFj relationship). Another told me that the dual was not a "warm" person (ENFp-ISTp).
Please tell me your thoughts.
