Sure. This just comes from my observation of him.Could you elaborate on this? If there's yet another good reason for me to keep my Fi from people, I would love to know. It's always good to hear how I come across.
He is not given to talking about how he feels. Instead he has incorporated social attitudes of what works to keep things moving. Kind of like what you described in having a script of Fe-responses for certain settings? He does that. At best, stating his innermost feelings is irrelevant to him. They only matter to him so why share them? He doesn't see the point in doing so. At worst, verbalizing his feelings, is a scary thing for him. His voice changes and he is well, for lack of a better word, naked. I've learned to handle these moments with some delicacy because I know I am one the only person that he has revealed some highly personal and intense emotions to.
I hope this made sense. I don't think it's a matter of not revealing your Fi, it's just finding the right people to do it with. There is a parallel with Ti, it's hard to put into words, even harder to share with someone else. It's personal in a way that really doesn't yield to a verbal explanation. It makes it really hard to let anyone 'see' that part of me. When I do finally share it, I want it to be valued, listened to, and not belittled even though I'm fully aware that it only has the greatest value and importance to me. That's why I said I can understand about not wanting to share Fi.
