Hi Sektor,

I don't think there is anything strange about this. It really comes down to how disruptive that behavior becomes.

In a sense, even between people, one is often attracted to a fictional version of the person initially. We all present ideal versions of aspects of ourselves to others and, in turn, interpret others on the basis of limited knowledge. Make-up, clothing, focusing only on exciting experiences - these are all ways we communicate a limited and attractive representation to others - a fictional representation or window on who we are. Fictional characters are often intentionally made to fill very specific niches and to represent exaggerated or prototypical features. That can be a villain that the audience immediately dislikes - it can also be a love interest that the audience can empathize with. Fiction would have no power if it wasn't able to move the audience to some feeling and consideration and so there would be no love interests if we couldn't at least relate to the romantic tension.

Now, if you want to look at this in an applied sense, perhaps it would be good to consider someone who is 'in love' with a fictional character and limits their romantic feelings for real people. While that can be done in a socially harmless way, I think it would be a case seriously worth some exploration in a counselling/therapy setting, as it could very well reflect significant, deeper issues related to socialization and intimacy. People have a remarkable ability to repress their own problems, so we owe it to ourselves to engage in self-examination when we begin engaging in habits that could reflect this.
