hi
so, just to start with your functions... in case you aren't familiar with the shorthand yet, it's an uppercase letter for the MBTI letter (I/E, S/N, T/F, J/P) and then a little i or e after it to indicate whether it's introverted or extraverted - so extraverted Feeling is Fe and introverted Sensing is Si:
you're Fe Ni Se Ti
he's Si Te Fi Ne
i think there are a lot of ways to look at it... some people (and websites) will tell you that you and another person will have an easier time if you share certain functions, and some will say others. but there are a lot of "compatibilities"... but personally, i don't find that either sharing or not sharing those functions makes things overall any more difficult - if you share, that's great, it might be easier to see where the other person is coming from... but you also might share the same blind spots. if you don't, you might have a little more struggle seeing where the other is coming from, but you're more likely to help balance one another out.
in truth,
things seem to depend a whole lot more on personal life history and overall attitude than in type matchup. i bold this because it's so much more important than type differences, and while i think type can be really helpful in understanding a relationship, please don't in any way think you're bound to have a difficult relationship because of it. if you care about and have a lasting bond with the other person, any type matchup can play to your advantage.
so, anyway, onto the theorizing -
- when we check out your types, obviously there's the J-J match - which can manifest in great things like having a really easy time sharing personal spaces because you're both probably more attentive and tidy than a lot of people, and can also be a little bit of a blind spot in that it might be harder as a couple to adapt to changes, and individually in terms of including the presence of another person in your life.
- in terms of Si, his dominant function, and Ni, your auxiliary (2nd) function, you guys can play a good balance with Sensing and iNtuition - he will probably be more attuned to past ways of doing things - what has worked well, etc. - and very dependable. you will probably tend to see new ways of doing things, and have a good sense of what is likely to happen, though sometimes you might find it hard to give concrete evidence for things you see playing out in your head through the use of iNtuition.
- a more likely clash but even greater balance that may manifest is between your Judging functions - Thinking and Feeling. having Fe, you are likely to have really awesome people skills, and to be a natural at creating and promoting harmony between people - including the two of you. you will probably be the lead "peacemaker" in the relationship. with Te, he will be more likely to say things direct and truthfully, which can probably be less appealing to you sometimes (or good sometimes, because he may say what you feel but did not want to voice.) he will also probably be very good at streamlining things, and organizing, but he may potentially infringe upon you accidentally and do or say something that seems hurtful or to leave you out (which is probably totally unintentional.)
- and finally, of course, as an I, he will probably need more alone time than you as an E. though i see you have a little e, so maybe that won't be so much of a problem
anyway, those are just my initial thoughts. it's entirely possible that none of the things i talked about will become present in your relationship, but i think those are the major points of contention/balance that i can see. overall, i feel like dating a person who is significantly different from you in type can be a little difficult sometimes but also can make you a much better person, because it helps you look at yourself in a whole new light.
