When 2 people agree to be together, they make that decision with their conscious minds; however, the unconscious part of our minds (our love-type), may have other ideas, as it holds all our unresolved needs and issues - and if those needs aren't met, they can manifest as disruptive behavior in the relationship. For couples with compatible love-types, this is less of a problem as there is more inner synchronicity. But if you're a couple with persistent issues you just can't explain, then it's time to look at your love-types and the joint pattern of disharmony that is being unconsciously created - and do something about it.
