There could be several reasons why your ex changed his Instagram settings to private after the breakup:
Privacy and Boundaries: After a breakup, people often seek privacy and space to process their emotions without the added pressure of public scrutiny. Setting their Instagram account to private allows them to control who can see their posts and follow them, giving them a sense of control over their online presence.
Moving On: Changing Instagram to private might be a way for your ex to signal that he is moving on from the relationship. By limiting access to his profile, he may be trying to create distance and avoid potential interactions with you or others associated with the past relationship.
Emotional Healing: The end of a relationship can be emotionally challenging. Going private on social media can provide a sense of protection and help prevent unwanted comments or messages that might be hurtful during this sensitive time.
Avoiding Unwanted Attention: Your ex might want to avoid any potential drama or discussions related to the breakup. By keeping his account private, he can minimize the chances of people, including mutual friends, speculating about his personal life or the reasons behind the breakup.
Creating a Fresh Start: Switching to private can be a way for your ex to establish a fresh start online, separating himself from the past relationship and creating a new online identity.
Blocking Mutual Friends: Changing the account to private might also involve blocking mutual friends or acquaintances to limit their access to his posts and avoid any unnecessary reminders or mentions of the past relationship.
It's important to remember that social media behavior can vary from person to person, and the specific reasons for your ex's decision might only be known to him. As tempting as it may be to analyze or speculate about their actions, it's usually best to focus on your own healing and well-being after a breakup.
If you find yourself struggling to cope with the aftermath of the breakup or any emotions related to the situation, consider seeking support from friends, family, or a therapist who can help you navigate this challenging time. Taking care of yourself emotionally is crucial during this period of transition.
