When someone says they are an only child but have a sibling who acts as if they don't exist, it typically means that they have a sibling, but their relationship is strained or distant. This could be due to various reasons, such as:
Estrangement: The siblings may have had a falling out or a significant disagreement, leading to a breakdown in communication and a lack of acknowledgement from the sibling.
Family Feuds: There might be ongoing family issues or unresolved conflicts that have caused one sibling to distance themselves from the other.
Emotional Distance: The siblings may have grown apart over the years, leading to minimal or no interaction, making one sibling feel like they are essentially an only child.
Personal Issues: The sibling who is acting as if the other doesn't exist might be going through personal challenges, such as mental health issues or substance abuse, which affects their ability to maintain relationships.
Parental Influence: It's possible that parents or other family members have played a role in creating or exacerbating the distance between the siblings.
It's important to note that every family dynamic is unique, and the reasons for such behavior can vary significantly from one situation to another. Feeling like an "only child" despite having a sibling can be emotionally challenging and can lead to a range of emotions, including confusion, hurt, or a desire to reconnect.
If you find yourself in this situation, it may be helpful to seek support from friends, other family members, or even a therapist to process your feelings and find ways to address or cope with the situation. Additionally, if both parties are willing, family counseling or open communication could potentially help bridge the gap and improve the relationship. However, it's essential to approach such situations with sensitivity and respect for each person's boundaries and emotions.
