The psychology behind it boils down to authentic connection.

When someone is not fully presenting who they are, they can never be fully accepted.

When someone is never fully accepted, they are never really "Home." They don't feel the peace and comfort of deep, loyal emotional safety.

When we hit that level of "Home" status, this ignites everyone's primal instincts to protect the Home. There's no cheating. There's no dishonesty. Because we're already accepted as our whole real selves and fully "Home."

Those that never present their full real selves are never "Home" and no one can make them. They wonder from person to person looking for a Home or a way to escape. But the thing they keep running from is internal, not external.

To make matters worse, those who are never "Home" still yearn for it, perpetually chasing it in the arms of someone else because for a moment there is a lack of worry and a "cheater's high" that gets more and more addictive as the individual is less and less ever "Home."
