It's challenging to determine the exact reason why your ex-boyfriend blocked you but did not block his other ex without knowing the specific circumstances and his thought process. However, there are several possibilities to consider:
Different Relationships: Your ex-boyfriend's relationship with you might have been different from his relationship with his other ex. The dynamics and emotions involved in each relationship could have led him to handle things differently.
Emotional Impact: The breakup with you might have had a more significant emotional impact on him compared to his other ex. As a result, he may have chosen to block you as a way to cope with his emotions and protect himself from further hurt.
Respect for the Other Ex: It's possible that your ex-boyfriend has maintained a more amicable relationship with his other ex, and they might have mutually decided not to block each other. Their breakup might have been less contentious, allowing them to stay in touch or be on good terms.
Avoiding Conflict: Blocking can be a way to avoid potential conflicts or complications, especially if there are lingering negative emotions between you and your ex-boyfriend.
Privacy and Boundaries: Everyone has different boundaries and comfort levels regarding maintaining connections with ex-partners. Your ex-boyfriend might have felt the need to set a boundary and prioritize his privacy by blocking you.
Social Media Strategies: People have various reasons for blocking or not blocking specific individuals on social media. It's possible that he has his own personal reasons or strategies for managing his social media contacts.
Change in Feelings: Over time, his feelings towards you and the other ex might have evolved differently, leading to different actions regarding blocking.
Regardless of the reason, it's important to remember that each relationship is unique, and people handle breakups and emotions differently. If you're feeling hurt or confused about being blocked, try to focus on your own well-being and healing process. Dwelling on the blocking might hinder your ability to move forward and find happiness in your life. If you're struggling to cope with the situation, consider seeking support from friends, family, or a professional counselor.
