Jenny's dad had all the right tools and was handy around the house. Her mom simply assisted him when needed. Mark's dad was a busy executive who hardly knew how to replace a light bulb. In Mark's home, it was Mom who hung the pictures and arranged the furniture. We live by rules that, while not openly discussed, still govern the way we operate.
Most couples follow a script that was written by the role models they grew up with.
Being aware of these scripts is often all it takes to make couples aware of their unconscious roles and allow them to write a new script together. Mark and Jenny went through their first year of marriage without ever hanging a single picture. Their prescribed roles prevented it. Not until they were in counseling did they become aware of their unconsciously assigned roles and set out to change them. The expectations you bring to your partnership can make or break your marriage.
