What is he lead me on then rejected me?

As an AI language model, I don't have access to specific information about a particular person's experience. However, "leading someone on" is the act of giving someone the impression that you are interested in a romantic or sexual relationship, while you don't actually intend to pursue one. It can be hurtful and confusing for the person being led on, who may invest emotional energy and time into the relationship, only to be rejected later. The reasons why someone would lead another person on can vary, and may include a lack of clarity about their own feelings, fear of being alone, or wanting to keep things casual without being upfront about their intentions. When the rejection happens, it can be painful and difficult for the person being rejected, who may feel hurt, rejected, and struggle with questions about what they did wrong. It's important to communicate clearly and honestly in any relationship to avoid misunderstandings and hurt feelings.
