It is possible for someone with antisocial personality disorder (ASPD) to get married, start a family, and appear to hide their true nature from loved ones for an extended period, possibly until old age or sickness. People with ASPD can be skilled at deception and manipulation, which can enable them to maintain a facade of normalcy in their relationships.
However, it's essential to recognize that each individual's experience with ASPD varies, and not everyone with this disorder will follow the same pattern. Some individuals with ASPD may not be interested in forming long-term relationships, while others may struggle with maintaining them due to their difficulty with empathy, emotional attachment, and impulsive behavior.
If someone with ASPD does manage to maintain a long-term relationship and family life, their ability to hide their true nature may depend on various factors, including their level of self-awareness, intelligence, social skills, and the level of scrutiny or involvement of their loved ones. Additionally, the support network around the person and their willingness to overlook or rationalize concerning behavior can also play a role in concealing their true nature.
It is essential to note that ASPD is a complex personality disorder, and those affected may exhibit a range of behaviors and traits, which can differ significantly from person to person. Seeking professional help, such as therapy and counseling, can be essential for those with ASPD to address their condition and work towards healthier relationships and personal growth. If you suspect someone may have ASPD or are concerned about someone's behavior, it's best to encourage them to seek professional assistance.
