i'm an infp female married to an intj male. maybe i can offer some kind of insight here (or not)
i know that intj brain of yours wants a specific list of complimentary traits followed by a list of contrary ones but that aint how i work so deal with it!
we oppose each other in many ways. much of the time i feel that he thinks i am too emotional and will brush aside my feelings as if they don't matter because he thinks i'm overreacting (and even if i am, i think he should still at least try to acknowledge my feels). over time we have learned to communicate better with each other but it has taken much practice and things still turn into squables just because we read each other wrong way too often. you know that whole infj mind/feels/radar thing... yeah, i don't have that. and my emotions can and usually will misinterpret his behavior. and his overthinking can and usually will misinterpret my emotions.
he is very straightforward where i am wishy-washy. he likes to have an agenda where i like to go with the flow. he despises loud music and i love it. he is very self centered and i feel i cater to his needs instead of there being an equilibrium. sometimes i feel totally neglected and because we both suck at reading this, and i suck at saying this, he is totally oblivious to me feeling this way.
but for every opposition between us, there are many good similarities. we both cherish time to ourselves. we both love quiet time, me to daydream about unicorns and butterflies and him to plot world domination. we are both very sensitive, even though he tries to hide this. and as in infp i think i'm pretty good at understanding this as we are extremely sensitive. we both care deeply about what matters to us. and aside from this we also have a good deal of interests in common.
but just keep in mind that type doesn't mean shit when we're talking relationships. even friendships. its all a learning process and you have to invest time and patience to get to know each other and also to get to know how each one of you 'works'. Even though i have some dom Fe going on, it aint that jedi-mind powers and super feels of an infj, so i recommend that you both talk more and assume less.
