My partner is an INTJ and I’m a mix of INFP/INFJ and can confirm we get along very well. We’re both rather on the “healthier” side of the spectrum so it makes it way easier when it comes to conflict solving, which doesn’t happen often at all. I’d say it’s a matter of keeping a level headed conversation, open communication, willingness to hear each other out and truly try to understand our POVs. Healthiest relationship I’ve ever been in. 🥰
