To answer the question of can one’s bipolar diagnosed partner be faithful, one must understand what the disorder is and what makes it likely that they might cheat on you.

What is Bipolar disorder?

Bipolar disorder, according to the American Psychological Association in the DSM- V, categorizes Bipolar disorder as a mood disorder that is marked by  intense emotional states that typically occur during distinct periods of days to weeks. 

The disorder is characterized by three main symptoms that can occur which is manifested in the individual’s behavior and mental state. 

  • Mania

While experiencing mania, a person with bipolar disorder may feel an emotional high. They can feel excited, impulsive, euphoric, and full of energy. 

This may pose a threat to their psychosocial functioning like carrying out responsibilities or making rational decisions. 

They often engage in risky behaviours, for example, spending sprees beyond financial capacity, engage in risky sexual behaviour like unprotect sex with strangers or infidelity putting their relationships at risky. 

  • Hypomania

Hypomania is similar to mania, but it’s not as severe. Unlike mania, hypomania may not result in any trouble at work, school, or in social relationships. 

  • Depression.

During this episode, one experiences symptoms of depression such as:

Deep sadness, hopelessness, loss of energy, lack of interest in activities they once enjoyed, periods of too little or too much sleep, suicidal thoughts

The disorder is further categorized into three types:

  • Bipolar I

Bipolar I disorder is diagnosed when a person experiences a manic episode and may include a depressive episode with possible neutral episodes where no symptoms manifest. 

  • Bipolar II

A diagnosis of bipolar II disorder requires someone to have at least one major depressive episode and at least one hypomanic episode. People return to their usual functioning between episodes.

  • Cyclothymic 

Cyclothymic disorder is a milder form of bipolar disorder involving many “mood swings,” with hypomania and depressive symptoms that occur frequently continuously for at least two years.

Individuals with any type of Bipolar disorder face the risk of behaviors that may put them or others in face of physical harm or psychological distress due to their manifesting behaviour during their episodes. 

An individual in their manic episode may become reckless, unable to consider the consequences of their behavior, and may have a general carelessness towards their roles and responsibilities driven by impulse. 

Studies have found that individuals with bipolar disorder have a higher tendency to be controlled by their impulses.

Challenges in a bipolar relationship

Bipolar disorders are often found to have a lot of challenges due to the suddenness of the episode shifts. 

Your partner, especially one that is not under treatment- medication or therapy, can experience shifts in mood which come unannounced. This often causes a lot of misunderstandings and emotional distress. 

There is also the challenge of the manic episode which often includes high sex drive, and disregard of social constraints and consequences. 

Your partner may exhibit higher libido, disregard responsibilities such as work, parenting, or share responsibilities that has been discussed prior in the relationship which may cause a lot of tension. 

Distress may also develop during the diagnosed individuals depressive episodes where one may exhibit behaviours related to suicide or suicide ideation, they may cause worry due to their lack of appetite and sleep. 

Major relationship struggles arise when one partner has diagnosed mental disorder while the other partner struggles with boundaries and a fractured sense of self. 

Often partners who themselves struggle with ineffective emotional regulation, unresolved childhood trauma, unhealthy patterns of attachment styles are those that find themselves struggling more than others in relationships that have the other partner with a mental disorder. 

Oftentimes, people who have an insecure attachment style will find themselves struggling to make peace with their Bipolar partner’s manic episodes or depressive episodes. 

Cycling moods can be stressful for both partners. This stress may compound the challenges of managing differences in needs, wants, even libido.

Why is infidelity more common in bipolar relationships?

The high frequency or likelihood of infidelity in a relationship with an individual diagnosed with bipolar disorder is often regarded as Bipolar infidelity, though it is not a standardized term. 

It has been found that the likely cause of the infidelity is a combined result of the partner’s hypersexuality, impaired judgment, poor impulse control, and grandiosity brought on by mania.

To understand why it is more common one must understand what is hypersexuality. The Goodtherapy summarizes hypersexuality related behaviors in bipolar individuals as:

  • A sudden, unexplained increase in sexual feelings.
  • Overwhelming sexual urges that cause immense distress. A person might continue thinking about sex even when they don’t want to.
  • Feeling intense and painful feelings of rejection if a partner is not interested in sex.

It is this particular manic- related symptom that often causes strain in other aspects of the relationship which creates tension in the relationship. 

When one partner wants sex much more frequently than the other does, the partner who wants sex more often may feel rejected or ashamed and may sex out sexual partners from outside the relationship. 

At the same time, the partner with the lower sex drive may feel pressured and find themselves resenting their partner, fear that their partner may seek sexual gratification elsewhere especially if this has been a recurring pattern, and develop mistrust.

 Is it possible for my  Bipolar partner to remain faithful to me?

Having a partner who has been diagnosed with bipolar disoder doesn’t mean they will be an unfaithful partner, but it does make infidelity more likely, according to statistics. 

Infidelity for people with bipolar disorder is usually fuelled by mania meaning that the cause of the infidelity is not so much about the person but rather their symptoms. 

Specifically their  poor judgment, lack of impulse control and hypersexuality. In fact, “sexual indiscretions” are such a common marker of bipolar illness that this symptom is listed in the DSM-5’s diagnosis criteria. 

While Statistics on bipolar disorder and infidelity can make it seem like odds are stacked against relationships where mental illness is a factor. 

Fortunately, the most debilitating and risky symptoms of bipolar disorder are the easiest to treat. Mania-related symptoms in bipolar I can be managed through treatment- medication and therapy. 

Whether your partner goes to counselling and therapy alone or with you- in couples counselling- it is often advised that to have a healthy relationship with an individual with Bipolar disorder when you yourself struggle with issues related to attachment to seek out couples counselling to understand each other’s needs and establish boundaries in your relationship.

  • Support their care

Be it their therapeutic journey or their medication treatments, it can be immensely supportive and affirming to the individual if the partner seeks to understand and support their journey towards healing and managing their symptoms. 

It is also a way to affirm their own responsibility of the symptoms and their manifesting behaviors especially if both partners are serious of making things work for the long run. 

  • Couples or Individual counseling

When the going gets tough, you and your partner can seek professional help to regulate stress within the relationship. 

Through couples therapy, you can work towards learning skills and techniques that can benefit the relationships and each other’s needs.
