Yes, but think ESTJ, not ENTJ. There is a great degree of rigidity in the inferior Si. This can be the most difficult to deal with in an ENFP. When they aren't experiencing stress, they get along with everyone very well, easily adapting to everyone's needs and values. The "inner ESTJ" is the shadow of this personality: being flexible and supportive didn't work, therefore the ENFP switches over to an ESTJ mode which is bossy (Te) and rigid (Si), that admits no compromise, and insists on getting things done. In some cases, this can actually be OK, because if a matter can be resolved by facing it head on and doing the hard work needed to overcome it, then it is resolved and the ENFP has successfully handled things, if perhaps in a reactive and not entirely emotionally stable manner.
The inner ESTJ becomes an issue in relationships, because the stress that a relationship causes MUST be addressed by cooperation. While a real ESTJ is quite capable of resolving conflicts in a cooperative and constructive way, the inner ESTJ of the ENFP demands complete compliance. It's kind of an emotional blackmail: "Do what I want or I'll REALLY get upset." The primary reason for the emotionality is that the ENFP part never really goes away. The ESTJ side is in the service of an ideal (Ne) value (Fi), an almost holy quest, and the Te-Si directives are intended to satisfy that value. If you don't cooperate completely with an ENFP in this very stressed state, they will tend to start regarding you as an enemy, with someone who is against her ideals, and thus cooperation or compromise is unmerited.
I've seen even the most mature of ENFPs (multiple, not just one!) do this on various occasions. If a matter touches on one of their core values, one of the causes they FIGHT for, there is no "reason" to be had. You are either with them, or against them, and they will not respond to any sort of "meet in the middle" kind of language.
What is the real thing that is driving them to act this way? There is some key value that you need to honor and respect. This is Fi, though, and what they SAY the value is probably isn't the value. Rather there is some past experience (Fi-Si) in which they or someone they loved very much got hurt very badly, and the value is a reaction to that.
If this underlying cause is singular, and an ideal worth achieving and spending time on, then it isn't necessarily bad to just let them have their way and help them move things forward. As long as they believe you're on their side, you'll be able to contribute and show them better ways of accomplishing their goals. If instead there are multiple "causes", or the cause is really vague, or the cause is something that directly interferes with your relationship with each other, then the overall behavior will tend to be more neurotic, and there isn't much you can do, as there is nothing concrete to point at and say, "Hey, um, this doesn't make any sense." Relationship therapy MIGHT help, depending. The cause will always take precedence over your relationship. If the cause IS your relationship, that doesn't necessarily help either, as the ideal of the relationship will eventually collide with reality, at which point the cause becomes finding a better relationship.
FYI, what I'm describing necessarily sounds extreme because of the nature of the topic, describing how ENFPs break down. Most ENFPs are quite reasonable, and if your ENFP is young, then this is a side of her that she can grow into. ENFPs love constructive (Te) hobbies (Si) in which they can invest their time, and these kinds of activities help them grow into their inner ESTJ a bit more smoothly. If they're stuck instead neurotically cleaning the house, that is a stressor that will eventually blow up in some other form. ENFPs need to endeavor to figure out how to solve logistical problems without going into stress mode, because if they always go into stress mode to solve problems, they will be overall very unhappy.
