There can be several reasons why an ex might choose to block your friends as well:
Avoiding Contact: Blocking your friends could be a way for your ex to create more distance and prevent any form of indirect communication. They may want to move on from the relationship entirely and feel that keeping contact with your friends could lead to reminders of the past or potential discussions about the breakup.
Protecting Themselves Emotionally: After a breakup, emotions can run high, and your ex may be trying to protect themselves from potential emotional triggers. Seeing your friends' posts or interactions could remind them of the past relationship and cause unnecessary pain or sadness.
Seeking Privacy: Your ex might feel the need for some personal space and privacy. Blocking your friends could be a way to avoid having their activities or updates visible to someone from their past relationship.
Sending a Message: Blocking your friends could be a way for your ex to indirectly communicate their feelings or frustrations about the breakup. It could be a form of signaling that they want to move on completely and don't want any further connection to the people associated with the past relationship.
Misunderstandings or Negative Perceptions: In some cases, misunderstandings or conflicts may arise during or after a breakup, and your ex might develop negative perceptions of your friends. This could lead them to block your friends as a way to maintain a sense of closure and avoid any potential conflicts.
Social Media Cleanse: Sometimes, people go through a period of social media cleanse or detox after a breakup, and that might involve blocking or unfollowing not just their ex-partner but also their ex-partner's friends to create a fresh start.
It's essential not to jump to conclusions about your ex's intentions without having a conversation with them directly. If you feel comfortable doing so, you could reach out to your ex to gain a better understanding of their decision. However, if the breakup was recent or emotions are still raw, it might be best to respect their need for space and time to process the situation.
