Just bringing your post from wfm's thread to answer you here:

Actually, it's not odd for couples to become contextually co-D.
Remember, that your ACOA can create a tendency for you to be co-D, although that's a cycle that you can break. Perhaps you weren't even really co-D, except in context with your W.
Again, remember that co-D is a learned behaviour. That's why people can become co-D, even if they normally are not.
And, your W may have been otherwise co-D, and again, in the context of the M, developed co-D behaviours with you.
Remember, this is not a "wrong" thing. I want to say it's not a "bad" thing. It's not. But it IS potentially harmful and destructive to relationships.
By YOU changing your behaviours and removing any co-D traits by working on your positive growth, this will ensure that you keep yourself from engaging in co-D relationships again. Either your own co-D or that of a partner.
