There could be several reasons why your ex blocked you after you blocked him. Here are some possible explanations:
Emotional response: Blocking someone, especially an ex, can be emotionally charged. Your ex may have felt hurt, rejected, or angry when they realized you blocked them, and their immediate response was to block you in return as a way to protect themselves or regain control of the situation.
Avoiding contact: Blocking can be a way for individuals to create distance and avoid any potential emotional turmoil or conflicts that may arise from continued contact. By blocking you, your ex might be trying to move on and detach themselves from the past.
Respect for boundaries: If you initiated the blocking, your ex may have interpreted it as a sign that you wanted space and no contact. By blocking you back, they might be respecting the boundaries you set and not wanting to intrude on your decision.
Emotional healing: Blocking can be a part of the healing process after a breakup. Your ex might have blocked you to minimize reminders of the past relationship, allowing them to focus on themselves and their emotional recovery.
Mixed feelings: Your ex could be experiencing conflicting emotions after the breakup. Blocking might be their way of dealing with those emotions and preventing themselves from being pulled back into the relationship.
Protecting their social media presence: Some people choose to block their ex-partners to prevent them from seeing updates, photos, or interactions with new people. It could be a way for your ex to maintain privacy and avoid any potential jealousy or awkwardness.
Misinterpretation: It's also possible that your ex misunderstood your intention behind blocking them. They might have perceived it as an aggressive or hostile action, leading them to block you in response.
Remember that every individual is unique, and their reasons for blocking you might be complex and personal. It's crucial to respect their decision and focus on your own emotional well-being during this time. If you have the opportunity to communicate in the future, try to approach the conversation with openness and understanding to gain clarity about each other's feelings and perspectives.
