I'm an INFJ, and I mean, I'm a TOTAL INFJ. Everything they write about us is etched in my soul. I am wary of giving "typology" more power than it warrants in general, but I have to concede its applicability to me. It is completely consistent.
I am also finding complete consistency in the good/bad of typing in my relationship history, to wit:
I have been deeply involved with three ISTJ's. All three were disastrous.
I lived with an INTJ for 5 years. In the end, it turned out not to be, but it wasn't nearly as bad.
I am strongly attracted to an INFP at this time.
One of my best friends is an INFJ, like me, the first female INFJ I've ever been close to. And another of my best friends, a woman, is an ISTJ --- but we are not romantically involved in any way, and this seems to work out just fine.
At any rate: my conclusion is, ISTJ BAD FOR ME!!! (or, one might also say, ME BAD FOR ISTJs!!!)
Is there any type that you, as an INFJ, just seem to do terribly with?
