Is it normal i think i’m in love with a fictional character?

If you're referring to asexuality then I'd suggest exploring studies performed worldwide on the matter. There's evidence that such people simply lack the chemical response that's meant to occur in the brain which causes sexual attraction. If you'd fully read what I said in my previous comment, you'd have noticed that I'd mentioned our brains wiring can form incorrectly leading to unusual outcomes. What you're describing is one such outcome.

The information I've posted has come directly from multiple sources and studies on the matter. If you don't like it then feel free to ignore it. And FYI attraction to fictional characters is an issue that can develop gradually or rapidly varying from person to person. It's fine to think what you will about a character. It however, is important to maintain a boundary between fantasy and reality otherwise the end result can be highly detrimental such as the situation in Japan where an increasing number of single people attempt to marry fictional characters and forgo any potential future they may have with real people. While they're free to do this, it is defined by mental health care workers as an illness.
