The 15 Most Common Reasons Why Adult Siblings Become Estranged

Family dynamics are complex and can change over time. Many siblings have a strong bond, but sometimes relationships can become fractured and lead to estrangement. This can be a painful experience for everyone involved, but it’s important to remember that you’re not alone.

1. Financial disagreements or conflicts over inheritance

Money is a common source of tension in many relationships, and it’s no different when it comes to siblings. Disagreements over money, loans, business deals, or inheritance disputes can create deep rifts. Resentment can build up over time, leading to strained communication and, eventually, estrangement.

2. Clashing values or beliefs

As we grow older, our values and beliefs can evolve, and sometimes these changes lead to clashes with our siblings. Differences in political views, religious beliefs, or lifestyle choices can cause friction and misunderstandings. It can be challenging to maintain a close relationship when you feel like you no longer share common ground, Psychology Today notes.

3. Perceived favoritism or unfair treatment by parents

If one sibling feels that their parents have consistently favored another, it can create deep-seated resentment. This perception of unfairness can fester over time and poison the relationship between siblings. Even if the favoritism was unintentional, the perceived imbalance can have lasting consequences.

4. Jealousy or competition

Sibling rivalry is a natural part of growing up, but sometimes those feelings of jealousy or competition can persist into adulthood. Whether it’s over career success, relationships, or other achievements, these negative emotions can create a toxic environment and drive siblings apart.

5. Long-standing unresolved conflicts or past hurts

Past hurts and unresolved conflicts can linger like emotional baggage, weighing down the relationship between siblings. If these issues are never addressed and resolved, they can continue to create distance and tension. Old wounds can resurface during new disagreements, making it difficult to move forward.

6. Differences in lifestyle or life choices

As siblings go their separate ways and build their own lives, they may find that their choices and lifestyles diverge significantly. One sibling may prioritize career and ambition, while another may focus on family and community. These differences can create a sense of distance and make it harder to relate to one another.

7. Lack of communication or emotional distance

Sometimes, estrangement happens gradually due to a lack of communication or emotional distance. Busy lives, geographic distance, or simply drifting apart can lead to less frequent contact. Over time, this emotional distance can solidify into estrangement, making it difficult to reconnect.

8. Betrayal of trust or violation of boundaries

Trust is a fundamental building block of any relationship, and its violation can be devastating. If one sibling betrays the other’s trust, whether it’s through a broken promise, a shared secret, or a personal attack, it can be incredibly difficult to rebuild that trust. The feeling of betrayal can lead to a complete breakdown of the relationship.

9. Substance abuse or mental health issues

If one sibling is struggling with addiction or mental health problems, it can strain relationships and create distance. The other sibling may feel overwhelmed, frustrated, or even resentful. The unpredictable behavior and emotional turmoil associated with these issues can make it difficult to maintain a healthy connection.

10. Manipulation or controlling behavior

Sometimes, one sibling may try to control or manipulate the other, using guilt, emotional blackmail, or other tactics to get their way. This toxic behavior can erode trust and create a power imbalance in the relationship, leading to resentment and eventually estrangement.

11. Conflicting parenting styles or disagreements over child-rearing

When siblings become parents themselves, their different parenting styles can become a source of conflict. Disagreements over discipline, values, or lifestyle choices for their children can create tension and strain the relationship between the siblings.

12. Dramatic life events or crises

Major life events like divorce, illness, or the death of a parent can trigger a range of emotions and reactions in siblings, HuffPost explains. These stressful situations can sometimes expose underlying tensions or unresolved issues, leading to conflict and estrangement.

13. Personality clashes or incompatibility

Just like any other relationship, sometimes personalities simply clash. Siblings may have fundamentally different temperaments, communication styles, or interests. Over time, these incompatibilities can lead to growing frustration and a desire for distance.

14. Unrealistic expectations or idealized image of the relationship

Sometimes, we hold onto an idealized image of what our relationship with our siblings should be like. We may expect them to be our best friends, confidants, or unwavering supporters. When reality doesn’t match our expectations, it can lead to disappointment and resentment, driving a wedge between us.

15. Simply growing apart

Sometimes, siblings simply grow apart over time. As we get older, our lives change, our interests shift, and our priorities evolve. We may find that we have less and less in common with our siblings. This natural drifting apart can be painful, but it’s a common experience for many adults.
