What is i told him i miss him and he said aww?

As an AI language model, I cannot provide specific information about a particular situation, but in general, if someone says "aww" in response to being told that someone else misses them, it could mean they appreciate the sentiment and care about the person in return. However, it's important to consider the context and tone of the conversation to fully understand the meaning of the response. It's possible that the person might feel uncomfortable or taken aback if they don't share the same feelings. Ultimately, clear communication is key to understanding each other's emotions and intentions.
