In order to understand how bipolar disorder can affect relationships, we need to look at how the two main episodes affect a person’s personality and behavior.
When someone is in a manic state, they are often very irritable. This may cause them to disagree with their partner, and sometimes cause them to look for fights that aren’t really there. Furthermore, this type of aggression is responsive to mood stabilizer medication.
Manic episodes also cause patients to partake in risky behaviors, such as binge drinking or gambling sprees. These impulsive behaviors may cause a lot of turmoil in a relationship.
Depressive episodes tend to cause the person to become very depressed and less communicative. They may be very weepy and feel hopeless. During these episodes, people may pull away from their partner. They may also seem so lost and sad their partner feels overwhelmed and unable to help them.
