It's funny that people consider Fe to be lying and falsehood, because, in all honesty, I tend to view Fi as being hypocritical and self-absorbed. I'm sure Fi cares a lot about people, but it seems unwilling to accommodate them, and it usually won't even bother to explain why it won't accommodate hem. Instead they'll move the discussion towards something else, or conclude that it's "pointless" to talk about. Like, you want me to go out of my way to accomodate you, but you can't even explain why I should be doing this? That's probably, like, one of the few things I need.
I suppose it's that I'm supposed to have the passion or inner drive to do whatever it is you want without needing to talk about it. I'm not entirely capable of figuring out what people want even when they won't tell me. That being said, if someone tells me something is "fine" I'm going to take them at their word. It's like, the minimum I need, not to be told things are "fine" when they clearly aren't. (And how is that not dishonest?)
It doesn't seem fair that I should put in so much effort, and then when it comes to what I ask them to do, they act as though I'm imposing some unreasonable hardship. If you want me to respond to your moods, and engage with them, and "support" you, I'm going to need you to at least tell me what the hell is going on in your head at least some of the time. What is so unreasonable, unfair, or oppressive about that?
Granted, some of that is Ti, not Fe.
