The biggest culprit to the common decline in your relationship with your body and with others is codependency.
When we are born, the first thing our parents do when we cry is put a nipple or a bottle in our mouths. At that point we become dependent on food to sooth our pains.
At the same time, when a couple gets married, they come into the relationship as independent people (or so they think) only to grow emotionally codependent with their partner’s affection, attitude and affirmations over time.
You then remain in a low-trust relationship because of the shame, guilt and failure that society has taught you about divorce.
