Well, without being an expert, I'm going to try to list the reasons why I think my crush is an INFJ:
First of all, keep in mind that I am an ENFJ. I have a special gift for capturing personality and understanding and empathizing with other people's feelings. I've always been like this and that has influenced my life, even directing my professional career along paths I didn't plan on.
Well, he is a lot like me in that, he is very intelligent, analytical, perceptive, empathetic, profound in his analysis, he is extremely diplomatic, he is a born mediator, he always tries to make everyone feel understood and important. I can't give you more details but part of our job involves having those qualities and that is why we both do the same thing.
When we met I had the feeling that we connect very quickly, sometimes we understand each other with a look or at least I feel that. He is able to read me with amazing ease, but so am I, although he may not realize it so much because my extroversion sometimes makes me seem somewhat innocent, but I'm not.
And I know perfectly well that he is an introvert, he doesn't like to go out much, he doesn't like parties and noisy places, but he is sensitive to music and he likes interesting conversations. He likes to talk to me about his feelings, but without talking about them explicitly, in an indirect way but that I immediately understand. Sometimes he looks at me intensely as if trying to read my deepest feelings, I keep looking at him mischievously and I think that he likes it and it disconcerts him at the same time. I smile a lot and I know he likes it, he told me. He secretly takes pictures of me and then he mischievously sends them to me. We play to like each other but we both know it's just a game…or was it? I don’t know anymore...
The point is that in some ways we are very similar but I am very outgoing and he’s more silent and reflective. I have always been attracted to strange and eccentric introverts, always, they are like a magnet of sweetness and mystery for me. They bring me balance and calm to the permanent effervescence that bubbles in me, I adore peculiar and eccentric people, they fascinate me, I want to discover them, get to know them, delve into them and at the same time I love to disconcert them when they realize that there is another human being capable of reading and understanding them and who is also capable of expressing their feelings and affections so openly and without fear.
By the way, he is older than me, about 10 or 11 years, even so I think that the generational difference is hardly noticeable or I do not perceive it.
Thanks for reading me.
