Continuing on the Meyers-Briggs Type meme, I asked my wife, Michele to take the this personality test.

Michele is an ISFJ. You can read up on ISFJ description 1, and ISFJ description 2. It seems to fit her to a tee.

Next, I looked at the page on relationships between different types. I looked up the ENTJ/ISFJ relationship and found we have the duality relationship. After reading the description together we were quite pleased.

Here's a quote from the description:

These relationships are the most favourable and comfortable of all intertype relationships providing complete psychological supplements. Dual partners are like two halves of a whole unit. They usually understand each others intentions without any need to say a word. Dual will naturally protect your weak points and appreciate the strong ones without asking for anything in return. Interaction with your Dual allows you to be yourself without the need to adjust to your partner like in other relationships. This often saves both partners a lot of energy which they can use for their own interesting activities. Conflicts between Duals are very rare and if there are any, they are normally short lived and solved without pain. Your Dual partner will love you just for what you are and if there is such a thing as true love then it could probably only occur in relationships of Duality.

A number of people have wondered how our marriage of a geeky engineer and a flighty artist can possibly work. "You are so different.", people say. It appears that our differences are our strengths.

YMMV. Don't read too much into the intertype relationships, especially if it suggests that your marriage will implode and disinegrate...
