Thank you! It's pretty funny that you're the first and only person to respond, because my infj boyfriend's name is Jeremy haha And what you said is spot on!Gets along pretty well. Affection isn't hard to come by. Sex is usually pretty good. Kinda lacking in the "get someplace in life" area. INFP sometimes wants someone more "take charge." INFJ sometimes wants someone more nurturing. Someone would have to be delegated the "man of the house" for practical matters, or find a way to divide them up.
She was asking about INFJ boyfriend, not INTJLogically practical: Te compliments the weaknesses of Fi. INTJ is very responsible in matters INFP would not care so much for. Emotionally impractical: INFP's desire for reciprocity might not be matched by INTJ...or any other T type, unless the T type understands this need and not trivialize it. I would definitely recommend this relationship if both types are well developed.
