I tested INTJ for years, then got INTP. I then learned that many INTP test as INTJ. INTP is a better descriptor for me.

You have to remember this are just your preferences on how you with the world.

My GF is an INFJ, and her type with my type INTP, is called the golden couple. So check the INTP forums if you want someone to understand you.

My GF and I have a lot of similarities but the differences we do have, has allowed us to grow not only closer but to grow ourselves and learn from each other.

You shouldn't focus solely on MBTI, you should do a variety of other tests, like as my GF said "i'm more than a personality test", which I already knew, She's just in the initial stages of rebellion, where as i'm a master.

Enneagram is another interesting one, and it shows stages of healthy and unhealthy development of functions etc. So worth checking out.

Jung who was the one who "invented" the MBTI originally has some other cool stuff he has done, so I recommend anyone check him out.
