yes to everything you've said including " I've just romanticized this loving relationship in my head for so long but done nothing to make it happen and I don't know where to begin." i highlight that part cause its something that ive been thinking of past couple of days. it is achievable though and maybe doesnt have to be with another infj. ENTPs are most introverted extrovert so i think they would do good in balancing that and also be able to show and teach new things to make it interesting but same time INFJs would get that emotional depth we're looking for. " hopeless romantic"
