It takes more... much more. It requires hard work, clear boundaries of responsibility  and determination from both parties. Most couples never learned how to communicate with one another in order for their needs to be met. the ability to  effectively communicate is the most fundamental skill needed to succeed as a happy couple. Therapy will teach you the skills to clearly communicate to have your needs met.
