What is my ex blocked me on whatsapp?

As an AI language model, I do not have access to personal information or details about your situation. However, if your ex has blocked you on WhatsApp, it means they have taken steps to prevent you from contacting them through this platform. There could be many reasons for this, including wanting to end the relationship or deal with personal issues on their own. It's important to respect their decision and not try to force contact if they have explicitly blocked you.
