Codependent Relationship
A codependent relationship is one where one person's sense of worth and stability depends on rescuing, fixing, or managing the other. Care flows mostly one way, and both people lose track of where one ends and the other begins.
From the outside it can look devoted. One person is endlessly giving, the other endlessly in need, and the giver's whole identity rests on being the one who holds it together. Underneath the devotion is a quiet bargain: I'll manage your life so I never have to feel unneeded.
Melody Beattie described codependency as losing yourself in someone else's problems. In a relationship, that becomes a loop. The caretaker over-functions, the other person under-functions, and the closeness gets confused with control. Boundaries blur until your moods rise and fall on theirs. This blurring is sometimes called enmeshment.
Seeing the pattern is not the same as blaming anyone. Both people are usually doing what once kept them safe. The first small move is to notice where you end and they begin, and to let one of their problems stay theirs to solve.
