I'm an INFJ male, and I dated an INTJ female a two GFs ago. My advice is that there are times that your T really won't understand his F, and vice versa. You really need to learn to work together. NF/NT pairings are very, very good and rewarding, but like any relationship, it depends upon the willingness of the two parties to work on the relationship.
INFJ males are very sensitive, caring individuals. This tends to confuse some women (in my opinion) because in some cases, they haven't dated a guy like us. We are driven by our gut and what we feel. Where as you are driven by your gut and what you know to be practical. My INTJ GF would always be confused as to how I just knew things and she had to think on them so much, but the real answer to that question is, I spend hours upon hours of time anticipating each and every situation, and simply reacting when the situation presents itself, because I already thought of the possibility of it happening. In general, an INFJ only appears to be confused or not know what he/she feels about something when presented with a situation that they didn't anticipate occurring.
In short, if you can use your practical side to balance out his feeler and work together, you will have a very rewarding relationship.
I'm cuurrently broken up with an INTJ who I love, and who loves me, but says "love is not enough".
Essentially she is looking for someone for the "rest of our lives", and when I was asked if I could throw everything and everyone else away, to commit everything to "us" (we had been dating for 4 months), I baulked. It's my mission to touch people personally (my job too - remedial massage atm ), so I couldn't give that away in a snap.
How do all you lovely folk recommend I get through the wall of Te (she is easily the most fascinating, complicated, intelligent person I know that isn't over 50) back to her heart and into the moment?
The dissertations she writes me, full of logic and 5 year plans overwhelm me sometimes, as all I want to do is just hold her and show her how much that moment means to me, to be with her.
