Bipolar disorder, manipulation or lying? Understanding the difference from narcissism

He promises you the moon and the stars one day, ignores you the next. She lied to you about important things, then broke down in tears. You’re trying to understand: is it bipolar disorder? Manipulation? Outright lies? Or a narcissistic personality disorder?

The question is legitimate, and it deserves a nuanced answer. First, because you need to understand what you’re experiencing in order to protect yourself. Second, because people with bipolar disorder already face a great deal of prejudice, and it would be unfair to lump them in with manipulators. This article helps you make the distinction, without replacing a professional diagnosis.

Bipolar disorder, in a nutshell

Bipolar disorder is a psychiatric illness characterized by significant mood swings. According to the French National Authority for Health (HAS), it combines depressive episodes with episodes of elation (mania or hypomania), separated by periods of stable mood. The French National Health Insurance (Assurance Maladie) reminds the public that this is a treatable chronic illness with appropriate treatment and monitoring.

During a manic or hypomanic episode, the person may:

• to talk a lot, very quickly, jumping from one idea to another;
• sleeping very little without feeling tired;
• to spend large sums or make risky decisions;
• overestimating one’s abilities, making unrealistic promises;
• to be irritable, sometimes hurtful.

During a depressive episode, on the contrary, she may withdraw, lose all momentum, stop responding to messages, or feel useless.

These variations are not not chosenThey are not aimed at getting something from you. That is the essential difference with manipulation.

Is a bipolar person manipulative?

No, bipolar disorder does not make someone manipulative. A person with bipolar disorder can, like anyone else, exhibit manipulative behaviors, but this is not a symptom of the illness. A systematic review published in 2023 in theInternational Journal of Bipolar Disorders This shows how much stigmatization people living with this disorder, and their families, face. Automatically associating them with manipulators only fuels this rejection.

What we can observe, however, is:

• Broken promises Made in a phase of exaltation, sincere at the time, impossible to maintain afterwards.
• Hurtful remarks in a phase of irritability, often missed once the mood has stabilized.
• A denial of the illness at times, which can resemble bad faith.

These behaviors cause suffering for those around them, and you have the right to set boundaries. But their origin is different from that of a control strategy.

Is a bipolar person a liar?

Not by nature. However, certain behaviors can be perceived as lies: denying an expense incurred during a manic episode, downplaying a relapse out of shame, or recounting grandiose plans that will never come to fruition. Shame and the fear of being judged play a significant role. When a lie occurs, it often serves to protect oneself rather than to exploit others.

Conversely, in a manipulative or pathological liar, lying is a tool It serves to gain admiration, money, power, or to exonerate oneself. To better understand this profile, see our article on mythomania and our advice on how to know How to deal with a liar.

Bipolar, manipulative, liar, or narcissist: a table of differences

Here are some guidelines. They do not replace medical advice, but they will help you understand the situation.

Criterion	Bipolar disorder	Manipulative / Narcissist
Origin of the variations	Mood swings, independent of you	Relationship strategy, often linked to what you do or refuse to do.
Rhythm	Episodes lasting several days or weeks	Rapid changes, depending on the context and the audience
In public	The symptoms are visible everywhere	Charming in public, tough in private
After a crisis	Often guilt, regrets, a plea for help	Denial, role reversal, reproaches
Report on care	The treatment often stabilizes mood	No “treatment” will change the strategy if the person does not question themselves.
Profit	No profit sought	Control, admiration, material advantages

The key point: the consistency of behavior with an objectiveIf the “mood swings” occur precisely when you say no, when you see your friends, or when you make a decision alone, it is likely something other than a mood disorder.

Our article on the apparent “bipolarity” and the wickedness of the narcissist deepens this common confusion.

And is a schizophrenic manipulative?

This question comes up often. Schizophrenia is a psychiatric illness that affects the perception of reality; it does not make someone manipulative. As with bipolar disorder, those affected are far more often victims of prejudice than perpetrators of manipulation.

When the two coexist

Sometimes a person suffers from a psychiatric disorder et has manipulative, narcissistic, or paranoid personality traits. In this case, treatment may stabilize mood without changing relational behavior. It’s a complex situation that requires a professional perspective. Our article on the manipulative paranoid personality can shed light on another profile that is often confused.

What you can actually do

Whatever the explanation, your well-being matters. Here’s a 6-point approach:

1. Describe the facts, not the labels. “He insulted me in front of the children,” rather than “he is bipolar” or “he is a narcissist.”
2. Observe the context. Do these behaviors appear in episodes, or in reaction to your choices and your autonomy?
3. Set clear boundaries. An illness explains a behavior, but it does not oblige you to accept everything.
4. Encourage the person to seek help if you suspect a mood disorder, without using it as a weapon in arguments.
5. Protect yourself first. If you are subjected to humiliation, threats or control, this constitutes psychological violence, regardless of the cause.
6. Seek support for yourself. Relatives of sick people, as well as victims of manipulation, need a space for themselves.

The signs that should alert you, whatever the cause

You don’t need to know “what’s wrong with him” to recognize that something is wrong. Certain signs justify taking precautions, whether or not there’s an underlying illness:

• You are afraid of his reactions and you adapt your entire daily life to avoid them;
• you are regularly belittled, insulted or threatened;
• he or she controls your money, your phone, or your outings;
• You feel increasingly isolated from your loved ones;
• you constantly doubt your memory or your perception;
• Excuses, when they exist, never change anything.

These elements describe a relationship where you are no longer safe. An illness may partially explain them; it does not make them acceptable.

Living with a loved one with bipolar disorder: keeping your place

If your partner has been diagnosed with bipolar disorder and is receiving treatment, the relationship can absolutely work. A few key points can be very helpful:

• Discuss it during a stable period This is the best time to agree together on what you will do if a crisis approaches.
• Identify the warning signs Symptoms include decreased sleep, unusual spending, and irritability. Identifying these early often prevents escalation.
• Don’t become his caregiver You are her partner, not her doctor. Medical follow-up remains her responsibility.
• Take care of yourself Family members often become exhausted without realizing it. Family associations exist to support them.

What distinguishes a difficult relationship from an abusive one is the possibility of dialogue, acknowledging wrongdoing, and making adjustments. If this possibility doesn’t exist, or if every attempt backfires, it’s time to seek outside help.

Health rating Only a psychiatrist can diagnose bipolar disorder. If you have concerns about yourself or a loved one, talk to a doctor. In case of danger, call the 17 (France), the 112 or 3919 (France) (Domestic violence, free and anonymous).

F.A.Q

How can I tell if my partner is bipolar or a narcissist?

Only a professional can make a diagnosis. A helpful clue: the variations of bipolar disorder usually last for days or weeks and appear in all contexts, whereas the manipulator’s changes in attitude often depend on the situation, the audience, and your reactions.

Can a bipolar person be a narcissist?

The two are distinct. The same person can exhibit both a mood disorder and problematic personality traits, but one does not cause the other.

Does treating bipolar disorder eliminate hurtful behavior?

It often reduces the frequency of episodes and therefore the behaviors associated with them. However, personality-related behaviors do not disappear with a mood stabilizer.

Should I stay with a bipolar partner who makes me suffer?

It’s a personal decision. The illness doesn’t force you to stay or leave. What matters is your safety, your health, and the couple’s ability to function within respected boundaries.

Conclusion

Bipolar, liar, manipulator: these words describe very different realities. Bipolar disorder is a treatable illness; manipulation is a way of relating that aims for control. In both cases, you have the right to protect yourself and to get help. If you need clarity in your relationship, you can discover the support offered to victims of manipulation.
