There can be several reasons why some exes try to stay in touch or be friends with their ex's family online:
Emotional Attachment: During the course of their relationship, the ex may have developed close bonds with their partner's family members. Even after the romantic relationship ends, they might still feel emotionally attached to those individuals and want to maintain those connections.
Sense of Belonging: Being connected to an ex's family can provide a sense of belonging and continuity. They might have shared experiences with the family and feel like a part of their social circle, which they may not want to lose completely.
Shared Friends: Often, when two people are in a relationship, they become part of a larger social network that includes mutual friends and family. Staying in touch with the ex's family may help maintain connections with these shared friends as well.
Nostalgia: The ex might feel nostalgic about their past relationship and the time spent with the family. Maintaining contact online can be a way to reminisce about those memories.
No Hard Feelings: In some cases, the breakup might have been amicable, and there are no hard feelings between the exes or the family members. Under such circumstances, staying in touch can be seen as a natural continuation of the friendship and support that existed during the relationship.
Manipulative Intentions: In some cases, an ex might try to stay connected with their ex's family as a way to keep tabs on their former partner or as part of a manipulative strategy to potentially rekindle the relationship.
Comfort and Familiarity: Being connected with the ex's family can provide a sense of comfort and familiarity, especially during the post-breakup period when emotions may still be raw and uncertain.
It's essential to recognize that staying in touch with an ex's family online can be a sensitive issue, and the motives behind it can vary significantly from one individual to another. It's crucial for both the ex-partner and the ex's family members to communicate openly about their feelings and boundaries to ensure that everyone involved is comfortable with the level of contact maintained. In some cases, cutting ties with the ex's family might be necessary for the emotional well-being and healing process of all parties involved.
