There is some level of dependency in every relationship, especially in parent-child relationships. However, as outline above, codependency tends to operate more in the extremes.
While is it s normal to at times feel powerless, if you almost always feel powerless in your relationships that is more concerning.
If you identify with the symptoms of codependency outlined above it may not be impacting your relationship right now, but it likely will down the road. Mental Health of America talks about how people who have codependent tendencies tend to end up feeling hurt when their efforts/work are not recognized by their partners.
A sign of codependency is also having your sense of purpose tied up in your relationship, which can lead to feelings of sadness or worry when things hit a bump in the road.
Considering all this, if you believe you are in a codependent relationship it would likely serve both you and your relationship to seek out individual or couples therapy.
Substance abuse is also a very common component of a codependent relationship as it puts at least one person in a caretaking position, and another in a dependency persons’ position. Addiction to drugs or alcohol inevitably makes the codependent relationship much more difficult.
