Characteristics of Passive-Aggression
Because you can’t have an honest, direct conversation with a passive-aggressive partner, nothing ever gets resolved. They say yes, and then their behavior screams NO. They try to sabotage your wants, needs, and plans using a variety of tactics. We all engage in some of these behaviors some of the time, but when there’s a pervasive pattern of multiple symptoms, it’s likely that you’re dealing with passive-aggression.
Denial: Like all codependents, they’re in denial of the impact of their behavior. This is why they blame others, unaware of the problems they’re causing. They refuse to take responsibility for anything, and distort reality, rationalize, blame, make excuses, minimize, deny, or flat out lie about their behavior or the promises or agreements they’ve made.
Forgetting: Rather than say no or address their anger, they forget your birthday or the plans you’ve discussed, or forget to put gas in the car, pickup your prescription, or fix the leaky toilet. You end up feeling hurt and angry.
Procrastinating: They’re avoidant and don’t like schedules or deadlines. It’s another form of rebellion, so they delay and delay with endless excuses. They don’t follow through on responsibilities, promises, or agreements. If they’re unemployed, they drag their feet looking for work. You may do more job-searching on their behalf than they do.
Obstructing: This is another nonverbal form of saying NO. When you try to decide on where or when to go on vacation, pick out an apartment, or make plans, they find fault with each suggestion and won’t offer any of their own.
Ambiguity: They hate to take a stand. They don’t say what they want or mean. However, their behavior tells the truth, which is usually NO. This way they retain control and blame you for being controlling. As you might expect, negotiating agreements, such as in a divorce or child visitation plan, is exasperating. In addition to procrastinating, they avoid being pinned down. They may insist on “reasonable visitation,” and label your attempts to specify a predictable plan as controlling. Don’t be fooled. This only postpones negotiation when repetitive arguments can occur over every exchange of the children. Alternatively, they might agree to terms, but not abide by them. You can expect to be back in court.
Never angry: They don’t express their anger openly. In childhood, they may have been punished or scolded for showing anger, or were never permitted to object. Their only outlet is passive-aggressive, oppositional behavior.
Incompetency: When they finally do what you ask, you likely have to redo it. If they make a repair, it might not last or you’ll have to clean the mess they made. If they’re helping with house cleaning, their inefficiency may drive you to do it yourself. At work, they make careless errors.
Lateness: Chronic lateness is a half-hearted way of saying NO. They agree to a time, but show up late. You’re dressed-up, waiting to go out, and they’re “stuck at the office,” on the Internet, or watching the game and not ready. Lateness at work or delivering assignments is a self-sabotaging form of rebellion that can get them dismissed.
Negativity: Their personality may include pouting or acting sullen, stubborn, or argumentative. They feel misunderstood and unappreciated and scorn and criticize authority. They frequently complain and envy and resent those more fortunate.
Playing the Victim: The problem is always someone else’s fault. Their denial, shame, and lack of responsibility cause them to play the victim and blame others. You or their boss become the controlling, demanding one. They always have an excuse, but it’s their own self-destructive behaviors that cause them problems.
Dependency: While fearing domination, they’re dependent, nonassertive, indecisive, and unsure of themselves. They’re unaware of their dependency and fight it whenever they can. Their obstructionism is a pseudo attempt at independence. They don’t leave, but withdraw or withhold intimacy instead. An autonomous person has healthy self-esteem, is assertive, and can take a stand and keep commitments. Not so for someone passive-aggressive. Their behavior is designed to avoid responsibility for themselves and family, and sometimes they depend unfairly on their partner for support.
Withholding: Withholding communication is another form of expressing anger and asserting power passively. They may walk away, refusing to talk things over, or play the victim and say, “You’re always right,” shutting down the discussion. They’re unable to articulate what they want, feel, or need. Instead, they retain their power using the silent treatment or withholding material/financial support, affection, or sex. This undermines intimacy as a way to fight against their dependency.
There are a myriad of other things they might do, like slamming doors, giving away something of yours, or offering you dessert that you’re allergic to or when you’re dieting.
