So this question is what I'm really aiming at. In professional settings, I don't have much issue working with Fi. Mainly because there is a greater focus on both parties to get the job done. A neutral objective both Fi and Fe can get behind. I'm not a "There's a right way and a wrong way to do something" kind of person. Rather, does the completed work show quality? If yes, cool. I don't care how you got there. Keep it up.
But in my personal relationship with my ENFP (7w6) I'm discovering this Fi/Fe is where we have the most struggle communication wise. Fe hits at my vulnerable point and Fi is pretty strong with him. So, I can get exasperated with being misrepresented in his eyes. It's frustrating because I can see the way he is viewing me but I'm not hitting him in the right spot, so to speak so that he feels my concern, care, love. He knows it in his head but when he hears my Fe, he is conditioned to reject it as control or "guidance" or guilt.
[MENTION=5494]Amargith[/MENTION] said she was raised with Ti/Fe and she sounds a lot like my ENFP. Kind of rebellious toward Fe. Understandably. I just want to say I understand how it could come off as guilt tripping. Because the Fe user is bypassing Fi to get to what they think is more important - the whole. So, I get that. Yet, I have seen that Fi users don't really explain this to Fe users. They stubbornly reject it. Silently even. Then they feel guilty. Now, I don't understand that at all. Honestly. Guilt in itself is foreign to me. But guilt because you may be thought of as selfish (am I reading that right?) is hard to wrap my head around. My ENFP mentions he feels guilt a lot.
I tell him he doesn't owe me anything and I never want him to feel that way ever. We have spoken about it and I have told him that if he feels that from me that it would be the opposite of what I would want. I never want to control him. Never. Ever. It goes against everything I believe in. In that sense, it is hard to see your support be construed in that way. I understand it, but it feels like a rejection.
But if an Fi person wants to reach an Fe person at least halfway (ideally) they would do themselves and the Fe user a good deal of justice to say, "I need you to back up. You're on my junk."

Because it lets the Fe user know where the Fi person is emotionally, mentally, etc. It also will strengthen the Fe users confidence in the Fi user.
Fe doesn't want you to tow the line so much as know where your lines fall. At least, if they respect the Fi user.
Because if you think about it, we can't know the collective unless we get a sense of the individuals in that collective as well. It may not be in depth but it's a toe in the water, so to speak. Sort of a "We still good here?" Cool. Let's keep going. Or "We still good here?" No. Okay what do we need change? This is frustrating to Fi because they may not know where they are, or what they think or feel about something when asked. Understandable. But, if that is the case, I don't think it is fair for Fi to hold it against Fe for going ahead with their desires if Fi doesn't make theirs known/doesn't know their desires/opinions at that time and that is a BIG DEAL because it happens. Fi doesn't voice their desires often but I have seen firsthand they can hold resentments without ever voicing displeasure. This can be a no win situation for Fe.
Notice I am using "we". On a side note: Kind of a big deal for me personally to include another in my life and the decisions I make in my life. So, in that sense, Fe can build it's own resentments for not being appreciated for how they are giving or showing value.
EDIT: I edited this to change some paragraphs around and after reading I'm a little sad because are Fi/Fe just at best supposed to "understand" mentally where the other is in intention without ever feeling deeply connected in that realm? Hmm.
