It's essential to remember that each person's actions and motivations can vary, so it's not possible to determine the exact reason for your ex-boyfriend's behavior without direct communication with him.
However, some possible reasons why he may have blocked you on Snapchat while keeping you on other platforms could include:
Emotional Space: Your ex-boyfriend might feel that interacting with you on Snapchat is more emotionally challenging or triggering than on other platforms, possibly due to past memories or associations.
Avoiding Temptation: He might be trying to create some distance and avoid the temptation of checking your Snapchat stories or messages regularly, as it could make it harder for him to move on.
Privacy Concerns: There may be certain aspects of his life he prefers to keep private and doesn't want you to have access to through Snapchat.
Different Use of Platforms: People often use different social media platforms for distinct purposes. He may prefer to communicate with you through messages or direct messages on other platforms while keeping Snapchat reserved for other connections or activities.
Miscommunication or Misunderstanding: It's possible that he blocked you on Snapchat unintentionally or by mistake. Sometimes, accidental taps or settings changes can lead to such actions.
Peer or External Influence: Someone else might have influenced his decision, such as friends or family members who advised him to block you on Snapchat.
Whatever the reason might be, it's crucial to respect his boundaries and give him the space he needs. If you are on speaking terms on other platforms, consider having an open and honest conversation about the situation if you feel comfortable doing so. Communication can help clarify any misunderstandings and pave the way for better understanding and closure, which can be essential for both parties to move forward.
