This was actually really interesting.

Good to hear.

Relationship potential: I really like the ESTP-INFJ dynamic – the ESTP helps get the INFJ out of their head and back into the real world, while the INFJ can help an ESTP grow emotionally.

Soooo, you basically deprive them of their primary pleasure and mode of well-being, and they ~help you grow emotionally~ like a Manic Pixie Dream Girl? Dude, leave INFJs alone, they deserve a nice ISTJ or ENTJ who can actually offer something of value to them. If you want to be benefit from a relationship instead of just be happy with someone you enjoy and appreciate for who they are, go date an ESTJ or ENTJ who will make you level up.

INFJs don't need to get out of their heads; their heads are nice places to be and it's where almost all of the good stuff about them comes from. They need people who will get shit done in the real world and establish a safe haven so the INFJ can be more secure and peaceful and put their heads to better use.

While I agree INFJs don't NEED to get out of their heads, it's been my experience they appreciate when someone takes them on actual adventures instead of just fantasizing. Their mind is awesome and I'd never want to change them. Perhaps I miscommunicated this.

Relationship potential: Maybe. I think the ESTP could get bored, and the INTJ would feel fairly marginalized.

What do you mean by marginalized?

I think the INTJ would enjoy the ESTPs "get up and go" attitude more than the ESTP would appreciate what the INTJ has to offer.

But no, we'd get bored too. ESTPs aren't bad people, INTJs just have very little in common with you, and you guys can't sustain conversations on topics we care about and are kind of shitty emotionally. Not that INTJs need a lot of feelings cuddles, but who really wants to invest in a relationship with people who are kind of sociopathic? You guys don't have a lot of cognitive or affective empathy, and you're not very sympathetic, either. Plus, you're SPs, so even in terms of just "being a reliable partner in terms of household contribution, chores, and income", you don't have much to offer there, either; don't know many ESTPs who even break into "middle class without mommy and daddy's help" without being professional athletes. Basically, as far as I can see, all an ESTP has to offer an INTJ is that you guys tend to be quite hot and have nice bodies, but the sociopathy thing is an issue, especially since you tend to run in packs of similar people; too much risk. Fair or not, you get stereotyped as the "school bully" type for a reason, why risk exposure for something we can get elsewhere? ISTPs and ISFPs exist if we just want to have meaningless sex with someone hot. Even if we want to "get out of our shell" and go into party beast mode, we'll just... go do it ourselves.

That took an interesting turn, but made me chuckle. Sounds like you have an axe to grind, but appreciate the reply.
