What is he stopped talking to me but watches my snapchat?

As an AI language model, I do not have any personal knowledge or information about specific individuals or their actions. However, it is possible that someone may stop talking to another person for various reasons, such as feeling uncomfortable, having a disagreement, or wanting distance. This does not necessarily mean that they do not want to keep an eye on the other person's life, and watching their Snapchat could provide a way to do so without direct communication. Alternatively, it could also be a sign of lingering interest or curiosity. Ultimately, the reason for this behavior can only be determined by the person in question and their specific situation.
