I am INFJ, a typical mysterious, secretive, deep, artistic, christian type of a girl. I have recently fell for a guy 8 years younger than me. I'm 31 and he is 23. Being INTJ, he is super smart and studying theoretical physics at a prestigious university. It seems to me that he has never been in a relationship. He seemed aloof and cold when we first met in person but we kept in touch by e-mail and when he came to Japan for his research project, we spent the whole day together in one city and we got along really great. After that we met up in Europe (one of the Wester european countries - this is a place where we live, for him study an for me work) and again spent the whole day together going to the museum and concerts. We are both very intelligent, inquisitive, have thirst for knowledge, and love arts and we just seemed to click together. Silence is not a problem for us. After this 2nd meeting, I touched his arm lightly and kissed him good bye and his face just lit up like a sunflower. I had never seen such an innocent face of a 23 year old guy. However, after this 2nd meeting, he just disappeared with no e-mails for over 2 weeks. He told me that he will be busy with his physics projects so I am assuming that he is focused on this. I want to ask you all INTJ men what kind of expectations I should have. Perhaps he is thinking that I am too old, perhaps he got side tracked with physics which requires tremendous mental energy. I just question myself these questions endlessly. My plan for now is to just not expect anything intense at this moment and keep in touch with him as a friend (perhaps meeting up every once in a while with no pressure) and see what happens. For him, his physics career seems like his top priority at this moment and I understand this. Does this sound reasonable? His mind is quite special and precious, I want to understand him.
