That is so neat that you did Meyers-Brigg before you got married!!
My husbands study partner in Jewish Seminary (Yeshiva its called) gave him this great book on the Enneagram. He had no IDEA how much it would help me understand my and a self and my fam better. I truly has helped me to better communicate with them (well that in conjuction with therapy and a lot of hard work ), and I hope it helps you as well.
I really hope this visit goes well for you...let us know *hugs*
