ISFJs and INFJs are secondary Fe users. However that doesn't mean they don't use Fi as a function. Going against the tone of the thread here... Aderack that's a perfect example of unhealthy Fi manifested.
It'll probably be influenced by Fe, but that's definitely an example of Fi.
This doesn't sounds like Fi. This sounds like people with issues.
I've known Ti's who get that unreasonable over their viewpoints, only they get angry, nasty and belligerent instead of crying. They were screwed up people too though.

Aderack: About your story. It's sounds like your playing games with her mind. Why not be a man of your word? If you say you don't mind, then change your mind... then just tell her that you changed your mind.
Knowing what person she is it doesn't seem very good to push her buttons and then blame her for being unhealthy because she couldn't take your confusing attitude. What do you expect from her? She's just a human like everyoen else.
I too have a relationship that is exactly like yours Aderack. It is a crime to disagree. But she can all she wants.
As with the selfish Fi, she does have very held values. She isn't afraid to tell people off if they are offending her. Which is a bad deal for me because I have to deal with her in a bad mood for the rest of the day. She is selfish with emotions and likes for all positive emotions to be sent her way, dumping all the negative ones on me like a waste management truck. FieryPheonix, could that be selfish Fi at work?
Whilst shopping for bedding for our new apartment, my former partner -- INFJ -- began to cry, right there in the store, when I suggested deep blue sheets to go with the maroon comforter she'd picked out.
People are murdered every day; starving around the world.
Children are abused everywhere, yet someone saw fit to actually cry about
There was an INFJ who claimed her husband was "abusing" her,
by knocking over the coins she carefully stacked on the kitchen table each night.
What's wrong with this picture?
If this is the best of possible worlds, what then are the others?

I think it has something to do with INTP's not being so much upfront in opinions. When my father (INTP) and I discussed interesting things, I tend to think that we are agreeing many things. But he seems to have alot of opinions that he deliveres when I'm off-guard, kind of a sneaky way. Exactly when my lighty P-side comes out. And it produces a reaction that seems very much like the ESTP shadow.
So it's not that you don't have the right to your opinion, just don't be so snakelike in your attitude and be more upfront. And also. Im guessing the anger from her (them) could also be that your opinions is of that sort that it is about controling their lives and making it easier for you, and not about aiding them (wich it should be, if you want a healthy relationship). Or it would be good to express it in a sensitive way that you are not there to piss them of but to aid them, with the opinions.
