No. Codependency is when one person relies on another for their needs, while the other neglects their own needs to support their partner, who does not reciprocate the support. A healthy couple gives and takes in turn, a codependent couple is one person leeching off another. Generally the supporting partner has low self esteem and derives their sense of self-worth from providing, but this becomes untenable as their own needs go unmet and they eventually burn out.
