Lol, funny, I just had a thinker (the INTJ), try to nonchalantly ask me how I was, and bring up my being in a relationship!. I told him he was failing miserably.
He admitted it was not his strong suit.
We confound them as well. I say give it a shot. I don't know if she is INTJ, but they really prefer directness, and respect it very much. They are private, though, you know, so she may not open up, till she feels absolutely comfortable.
