I had a different interpretation of OP's post. Phrases like "put the success of the marriage above their individual successes" and the like are more of a sentiment than a prescribed behavior. It's like telling your spouse "you're more important to me than my job". On the one hand, in my case it's true - my wife is more important to me than my career in a general sense - but on the other hand it's not like she's making me abandon my career to, like, wait at home and fawn over her or anything. But if that prioritization actually caused me to make sacrifices where I'm no longer happy, then that's more of the "path to misery" IMO. You can have a feeling of love strong enough to believe your spouse is the most important thing in your life, without being codependent. The codependency comes from the outcome: does this feeling cause you to abandon your own needs? To abandon your own pursuit of happiness? If not, maybe you do actually love the person deeply and you don't need to go worrying that you're in some dangerous, codependent relationship. Full disclosure, happily married 9 years now.
