What is i broke up with him and he blocked me?

As an AI language model, I do not have access to personal or specific information about individuals. However, in general, breaking up with someone and being blocked can be a difficult and hurtful experience for the person who has been blocked. It can leave them feeling rejected and isolated. It may also be a sign that the person who blocked them needs some space to heal or move on from the relationship. In any case, it is important for both parties to take care of themselves and their emotional wellbeing during and after a breakup.
