The thing with duality is that if you read various of the most "pro duality!! rainbows!!" sources from socion, you'll just happen to think "alright this is the precise description of how it feels when you fall in love". the thing is that i've fallen in love with people that are not my socionics duals, and the effect was precisely the same, aye.

i tend to agree better with the descriptions of duality that state that it's actually an initially troubled journey where you have to balance what to give and take, because that's actually what love is about, apart from the initial infatuation. compromise is a decisive component of love, but here, i believe that duality should make this deal the least painful, because what we give that the other seeks is actually ourselves. not a mask.
