If this was the meanest thing she said to you then she is not mean at all. Since you were not ever a "couple", despite the complements, etc, that was the point in the relationship that you needed to try to stop communicating with her. Complements don't always mean someone is "into" you. Many people give them out to everyone they talk with (but mean it) as a way to brighten other people's days. Perhaps those fantasies were about distracting yourself from yourself? It sounds like you need to learn to learn to love and accept youself. In a good relationship--we don't get overly needy, we learn to be as comfortable with ourselves when we are by ourselves as when we are together (you enjoy being together but also enjoy time apart). Sometimes if we need the other person too much then we can end up compromising our own needs so it is important to look at what is going on inside when a "relationship" doesn't feel right. Perhaps what happened it the wake up call you needed. Figuring out why you feel that way will help you have a healthier real relationship someday.
