Sometimes we get focused on solely on behavior.
On one hand, that is understandable because behavior is observable and measurable.
On the other hand, the motivation and feelings behind the behavior are vital but difficult to quantify and make tangible.
In one sense feelings are not right or wrong, they just exist. Our behavior is what counts.
But you can't separate them in living your life. You can't feel without it affecting your behavior and what you do will affect your feelings.
In one sense commitment to a relationship is vital for its success.
In another sense, for a relationship to work the commitment must be mutual.
