I believe every choice we make is our attempt to find ourselves. We unconsciously choose a path and the encounters on that path. If you can see each experience as something you have learned, it really helps. If, instead of feeling bad, you choose to ask yourself. I think you could say you learned not to get ahead of yourself and create expectations that aren't possibly the same as the person you are creating the expectations about.
Rejection is a word.
If you feel rejected, it is an extension of how you choose to feel about this. Think of this scenario. Learning the lesson This guy was probably attracted to you. He didn't force sex on you because you say you stayed together for two nights without sex. At least he didn't disappear after the first night.
