At the very least, couples that enter into treatment should have a desire to stay together and explore issues that prevent it from being a satisfying relationship and return to a better level of functioning.
Couples today are faced with challenges of previous generations, i.e. infidelity, poor communication, parenting and trust issues, as well as issues that have arisen in more recent years and since the advent of technology, including internet pornography, inappropriate text messaging, fluid sexuality, open relationships, and more. Your relationship, your rules. My role as a couple therapist is to help each couple navigate their own expectations, limits, and boundaries in a way that is neutral, understanding, and supportive.
