I spent the first year that I dated my fiance as a pygmalion project, and being the ISFP he is, he actually patiently tried to meet my expectations. I expected him to think the same way I did, treat goals and ambitions the same way I did, be oriented toward authority figures (of all kinds) the same way I was, and to appreciate things the way I did. I assumed people that in love had to be the same, and I unconsciously asked him to be an INFJ. It took a while for me to realize what I was doing, and how we can never be the same person. (Why would we want to be, anyway, I now ask myself?) We bring out the NJ-SP in each other, which is so good now that I have the words to describe it from type theory.
I am sure I have not relinquished my chisel completely, but since he also knows about type theory he can tell me to just let it be--and I can relax and enjoy a detailed veiw of a mind gloriously different from my own.
