Kianal, don't let some online quiz tell you a relationship can or cannot work. Individuals vary and that quiz can't possibly know more than you do. I think I got INTP when I took it (just for fun!), but it doesn't have much merit.
I think that some people who identify as introverts are not introverted at all, but merely shy/socially anxious, and blame this on their supposed introversion as a means to never break out of their comfort zone or grow as people. e.g - "should i go to this party? no, im introverted, i prefer being on my own..." when in reality, they don't go because they're anxious.
i say this because it's my own personal experience and i'm pretty sure i'm not the only one. i regularly scored INFP with 70%~ introversion scores on tests like this because i went in with the mindset that was i introverted and answered biased in favour of receiving that result. in reality, i hate solitary and being on my own for large chunks of time and always feel more energetic when around people, so it has to be wrong.
the INFP and INTP personality types come to a combined 5% total of the population. why is it then, that on epicmafia and other internet communities, this figure jacks up to like 50%? obviously, epicmafia isn't a representation of the population at large, but clearly something is wrong.
