Couples join forces with one another by forming agreements. Agreements are expressed in writing or verbally during very intentional conversations.
Most of us have never learned how to craft effective, explicit agreements. It is a skill we were never taught, even though it is fundamental to all relationships and a basic life skill.
This is a method I believe every committed couple should learn and use over and over again. It is also works beautifully with any two or more people who wish to make agreements that honor who they are and their relationship, and ensure that they end up in a Win-Win outcome.
