I'm married to an ISFJ ... and I'm lucky in that she is fairly flexible. Perhaps this is due to living with me all these years ... I don't know. She is open to a lot of the things I like to do, and I try to reciprocate with helping her around the house ... which I know is very important to her. Yes, she does have some set ways that are very difficult to circumnavigate, but I have a few core values of my own. I don't feel trapped with her, and we do not argue (too much ). Sometimes, however, I feel that she is really an INFJ. Go figure.
