Reading your posts, since I appeared on forum, I had no doubts that you’re NP. Then I found out that you are sensitive and probably one of your main functions is Fi. About I/E I wasn’t so sure. You seem to be open, but very reflective ( I think I read somewhere you wrote that you tend to overthink things).
I just read your questionnaire and it didn’t really change what I thought before.
I think distinction between INFPs and ENFPs can be tricky. Not only their functions are similar, but this I/E thing can be confusing.
ENFPs can sometimes behave like introverts. For example I know ENFP who sometimes can look like introvert, usually when there is something big happening in her life and she needs time to think about it on her own, but considering her other traits, how she concentrate on the outside world, easily take action to change it etc I’m sure that her type is ENFP
The same INFPs can behave as extrovert as they like to spend type with other people, it’s important to INFPs to understand them (and understand their feelings), they can also be the life of the party and be very open, like to exchange ideas, although more likely among their friends.
My best guess is that you are INFP like that
