Criticism vs. a legitimate complaint
A complaint names a specific behavior and its impact. Criticism attacks character — 'you never think about anyone but yourself' instead of 'it hurt that you forgot' — and the shift from behavior to character is what makes it corrosive.
Why contempt is in a category of its own
Contempt communicates disgust and superiority, not just frustration — and because it attacks the other person's sense of worth directly, it's the single strongest predictor researchers have found for whether a relationship ends.
Defensiveness as a response to the first two
Once criticism or contempt shows up, defensiveness — righteous counter-attack or playing innocent victim — tends to follow, and it blocks the actual repair that could happen if either partner stayed curious instead.
Stonewalling as the final stage
By the time stonewalling becomes the default, both people have usually given up on the conversation changing anything, which is why it tends to show up later in a relationship's decline rather than at the start of it.
The presence of these patterns occasionally isn't the concern — every couple slips into them sometimes. What matters is whether they've become the default response to conflict, and whether anything exists to counterbalance them, like genuine repair attempts and appreciation.
Recognizing all four in general is useful. Naming which ONE actually shows up most in your last three disagreements — not all four at once — is the harder, more useful thing to look at. Name that pattern, in OLENRI
