Hi Marianne. I like the concept (i.e. a partnership in health), but after working with several partners of a spouse who was NOT involved in becoming healthier the one thing I’ve learned is that the motivation of the “other partner” has to come from within. The “contract” that they share has its beginnings in their marriage contract in my opinion, and so the spouse should be supportive and helpful even without this type of agreement. If it takes this type of agreement for the partner to get this type of support from their spouse, I’m not sure it’s going to work in the long run.
Just my two cents.
