It is funny you mention the silence/moodiness/negativity. I am constantly battling the negativity i.e. nothing is going good or nothing good can come of a bad situation. Anyway, that is my INFJ to a T. I guess it is why we balance each other out, but I do hear that I am right more often than wrong. They often do not want to talk until I do not want to talk, which isn't often LOL! I suppose being married to my INFJ doesn't allow me to have a choice, but I throw myself at music and get away when I can.
Often, I have to be strong and make my INFJ realize when she is out of control or needs rebalancing. When I cannot win, I go to my laptop and find something else to put my mind into.
Cheers,
