I used to have a crush on many cartoon characters. Since I grew up in the anime community, I had my love for Hetalia fandom. The characters I was in love with the most was Romania.

It's still the same thing as crushing on fictional tv series characters. You especially have a lot of fan girls going gaga for Sam and Dean in Supernatural. Also the angels in Dominion (these are just two shows I know, but don't watch. tried getting into supernatural but I got bored with it.)

As of now, I cannot stop thinking about Archangel Michael from the "book that came from the middle east and is now popular around the world" (The title begins with a "B", but I don't want to discuss it and trigger a debate). I'm to the point where I get jealous when I think of him being with another human girl.

However, I'm trying to steer clear of getting too involved in my fantasy world in fear of me losing touch with reality.

You should talk to your therapist about this. You have to be really careful when comes to fantasy and your imagination.
