There could be various reasons why your ex is talking and trying to be friends with your friends:
Mutual connections: If you and your ex share the same social circle, it's natural for them to maintain some level of interaction with your friends, especially if they were close to them during your relationship.
Seeking support or validation: Your ex might be trying to seek support or validation from your friends after the breakup. They could be looking for reassurance or understanding during this difficult time.
Remaining connected indirectly: By being friends with your friends, your ex might feel like they are still indirectly connected to you, even if the romantic relationship has ended. This could be a way for them to stay in touch with your life post-breakup.
Genuine friendship: Sometimes, during a relationship, genuine friendships form between partners and their friends. After a breakup, your ex might want to maintain these friendships independent of the romantic relationship.
Spreading a message: It's possible that your ex wants to communicate indirectly through your friends, either to convey a message or to check on how you are doing.
Creating jealousy or discomfort: In some cases, an ex might try to be friends with your friends to create jealousy or discomfort, attempting to elicit a reaction from you.
Regardless of the reason, it's essential to focus on your well-being and emotional healing after a breakup. If your ex's actions make you uncomfortable or upset, consider having an honest conversation with them about your boundaries and feelings. You may also want to communicate with your friends about your emotions and ask for their support during this time.
Remember that everyone's motivations and reactions can differ, so it's essential to approach the situation with an open mind and empathy. If the interactions with your ex's friendship circle become problematic or distressing, it might be helpful to distance yourself from the situation and focus on building a support system that prioritizes your emotional well-being.
