Codependency is tremendously misunderstood. It's thought of as enabling addiction, but that's only codependency's shirttail. If you dig a little deeper, you find something much more complex and harder to nail down.
Codependency is understanding yourself through the eyes of another. In the classic case, it's a wife measuring her worth through her husband's eyes. When he sees her rescuing him from his drunken blunders he sees her as an angel, and on the strength of his worship she can continue with him for years. Of course, when he sees her as a conniving shrew, she shrivels and dies.
Codependency festers in hundreds of avant-garde hidey-holes, too. It's the man who whithers when his boss misunderstands one of his decisions. It's the child who crumples when she gets a B in advanced calc. It's the alcoholic who swells with hope when his wife reminds him how she still sees him sometimes.
Codependency is the engine of failure. There's no success in codependency because we can't control how other people see us. When they see us better than we are, we're set up for the failure pride brings. When they see us worse than we are, we're bled dry of the hope we need to take the hard steps each day demands.
It amazed me to realize God IS.
God's knowledge of Himself is accurate and complete. If I despair and vent my exasperation on Him, He realizes He is faithful. If I "feel lucky" and swell with assurance He's going to work some miracle for me, He knows He's the God He is, not the One I wish He were.
There's a quiet manipulation we all work on each other. We praise and correct each other to shape the way we're treated. God is not shaped by our praises and corrections. God IS. Amazingly, neither does God manipulate us. He very directly tells us Who He is, and whom He is willing to make us. He tells us what we can do for ourselves and what we can do for Him.
God IS, and that makes relating to Him the simplest thing we'll ever do ... once we figure out how to relate to such confidence.
