Seems like a good combination because the as the INFP as a guy would be like an INxP and the ENTP as a girl would appear to be an ENXP, - it's just this thing I've noticed personally tbh. Thinking too critically can be distancing for an INFP, but being too sappy like "aahhh! unicorns and fairies" can be a bit too fucking annoying* (mind the language) for a borderline rebel-fringe-of-society-loving-caring-yet-moody INFP guy as for myself.
Hey! at least it lasted... not to sound like a jerk, me and my elder brother (ENTP) barely have any proper brotherly connection and we avoid each other a lot. We avoid each other because we can fight a lot, and deeply/literally-insanely fight when we actually talk - though avoiding each other is destructive, it's not as destructive and we both know that. Anyway, we barely talk and when we do, it usually starts off heated and we can get really uneasy just by the vibes we give off and the general air.
It's like we're trying not to offend each other, out of the experiences and conflicts that have gone out-of-hand, and made me bitter. It's not what we argued about, it's usually the hardship of emotion I've found pursuing connections with my ENTP brother from him getting heated over little details making me and even him work around egg shells or have airy annoying laughs to any slightly serious remarks we make about each other or our flaws - and it can be really not genuine... not genuine is fake and annoying (trust me). It's hell for me and I hate having to do the occasional breather after going "what will happen now, oh..." .. it makes me feel like a stupid idiot.
But it's more the fact that he seems to never learn at the end of the argument and do his part and he doesn't actually listen to what I'm saying, when he comes at me after a stubborn rebuttal with his 'conclusions' of the whole thing. He tries to make these conclusions, without considering my argument and the implications that I'm willing to fix my own, if he just tells me like a human being instead of a dominating regime messiah.
As an ENTP with a borderline xSxx personality (after he evaluated his type), and a disruptive narcissistic personality to the degree of physical violence when he can't take criticism for his own opinion/ideas (which I suspect is very unusual for any type and is purely subjective), I'd say he's not the best example for the archetypal ENTP. But he's all I've got next to my ENxP sister ... we get along just fine.. or I just have had enough terrible conflict with my brother I can appreciate me and my sister's connection better.
I'm kinda drifting off the rails here, but I'm probably never going to talk to my elder brother the same way I talk to my elder sister, because my sister doesn't need to work on egg shells around me and is more carefree with how she feels and how she thinks about things, and is considerate of my emotions. It's not that hard to be considerate of emotions and genuine at the same time, you just have to understand the world around you as much as you critically understand it. I can't talk to my brother without having to constantly think about how the little things I say might flip him off so it's always constrained and forced. When I do say things you can see this little switch go off in his head like I had said something completely out-of-it, I don't know whether this is ENTP. But my sister has that but she takes in what I have to say rationally, and then, i understand that I may have just been looking at it in a subjective way. Though when my brother does this, he expects to "know" me and makes conclusions, whether rational or not, about "why I'd say that" - almost like he's paranoid. But most of the time, I'm fishing for criticism as well, because in a way I'm not sure of myself... almost always... so I don't expect everything to be taken literally, but I expect everything to be considered in a way...
Ott, I'm not a detail or rational person when it comes to relationships, unless I set out a topic to be like say psychology like now, but when it comes to most things I just want it to flow like anyone would want it to... I just don't want to walk around egg shells and I can sense when other people are doing it too. And if you have to be safe at the sake of being genuine/real it's not worth the effort, and it's torture..
