The idealization phase can last from a few weeks to a few years. It is important to remember that this phase is just one aspect of the borderline personality disorder diagnosis and that not all people with it will go through it.
Borderline personality disorder can cause people to feel unbridled love or infatuation, to regard someone as an infallible savior. This dichotomous nature can make maintaining relationships exhausting.
This usually begins with idealization or the “honeymoon phase,” where the BPD partner has you on a pedestal and believes you will never do anything wrong. This period can last a few days or go on for months.
People with BPD tend to have relationships that are intense and short-lived. You may fall in love quickly, believing that each new person is the one who will make you feel whole, only to be quickly disappointed. Your relationships either seem perfect or horrible, without any middle ground.
BPD splitting ruins relationships since the person can misconstrue the behaviours of others when their feelings are brought up in the relationship. Often, the borderline person is unaware of how they feel when their feelings surface, so they displace their feelings onto others as causing them.
Passionate and emotional – When a person with BPD loves, the love is deep, highly committed and loyal to the relationship. Even though there may be struggles with attachment and fears of abandonment, these are ultimately manifestations of love.
If you suspect you're someone with BPD's favorite person, they may exhibit the following signs toward you: Consistent need for reassurance. Intense declarations of their love or appreciation for you. Reaching out more frequently when you don't respond.
A BPD relationship cycle often consists of some emotional highs and lows that may leave you confused and frustrated. You might also see your partner experience unexpected bouts of anger, anxiety, or depression. They may love you and then suddenly reject you or get upset.
People with BPD may be sensitive to rejection and abandonment and are prone to splitting, rage, and impulsivity. If a person with BPD feels rejected or abandoned, they may end the relationship. However, this is usually followed by significant anxiety and regret and efforts to get back together.
It's very common for someone with this disorder to have intense, unstable relationships filled with drastic and quick-changing feelings. A person with BPD may fall in love quickly and assume that the other person will make them happy.
Borderline/dependent: A person with borderline personality disorder (BPD) is well-matched with a person who has a dependent personality disorder (DPD). The BPD has an intense fear of abandonment which is a good match for the DPD who will not leave even a dysfunctional relationship.
Results found in a 2014 study found the average length of a BPD relationship between those who either married or living together as partners was 7.3 years. However, there are cases where couples can stay together for 20+ years.
Borderline personality disorder usually begins by early adulthood. The condition seems to be worse in young adulthood and may gradually get better with age.
The only pairing I have seen that works well for and is healing for people with BPD is when they find a partner who is emotionally present, consistently faithful and loyal, unconditionally loving, but also sets boundaries. People with BPD can find rejecting partners and codependent partners fairly easily.
According to the DSM-5, BPD can be diagnosed as early as at 12 years old if symptoms persist for at least one year. However, most diagnoses are made during late adolescence or early adulthood.
Another hallmark of borderline personality disorder is having a favorite person—usually a family member, romantic partner, or someone in a supportive role, such as a teacher or coach. For someone with this type of BPD relationship, a “favorite person” is someone they rely on for comfort, happiness, and validation.
A split might often be caused by an event that triggers the extreme binary emotions that characterise BPD. Sometimes, these events might seem harmless or small to people without BPD, but they may in some way relate to previous trauma. This event might spark fears of abandonment, separation or severe anxiety.
People with BPD are often terrified that others will leave them. However, they can also shift suddenly to feeling smothered and fearful of intimacy, which leads them to withdraw from relationships. The result is a constant back-and-forth between demands for love or attention and sudden withdrawal or isolation.
People with BPD feel firmly attached to their favorite person and may depend on them for comfort, reassurance, and guidance. In many cases, someone with BPD may rely entirely on their favorite person. As a result, they may idealize them and expect them to always be available.
No. Borderline Personality Disorder and cheating are not connected, though certain symptoms of BPD could drive someone to cheat. That said, if you and your partner are willing to work through the challenges of BPD and go to therapy, then there is no reason your relationship can't succeed.
Many people with BPD have a strong desire to be close to others. However, fear of abandonment or a skewed sense of self may cause them to act impulsively or aggressively in an effort to keep loved ones close to them.
