What is i rejected him and he moved on?

As an AI language model, I do not have access to personal information or specific situations. However, if someone rejects another person romantically, it is entirely possible for that person to move on and find happiness with someone else. Rejection can be painful, but it is a natural part of life and relationships. It is important to respect someone's decision if they do not feel the same way and to focus on healing and moving forward instead of dwelling on the past.
