I knew the feeling of falling in love with a fictional character right before I discovered the Internet, I just didn't call it "waifu", I called it an "anime crush".
For this country which always expected that someday, whether you like it for not, you would always be married to a 3D person and have kids because of myriad of reasons such as not dying alone or just simply being a "Normal Ordinary Responsible Person", the thought of falling in love with these Japanese cartoon characters were simply at least an immaturity that will soon go away in time and at worst insanity that needs to be cured with socializing and beer and whatever "adult" things that needed to be done. You know, because being a piss-drunk and underemployed man who has too much children and too little budget to raise them properly is the height of responsibility and maturity. It isn't a stretch to say that all countries have this kind of imperative to have a biological family, maybe it just so happened that my culture had a lot more peculiarities on it than I should divulge because this post will be too long.
To cut to the chase, I was here because I wanted to express this feeling of falling in love in such a way that is considered an abnormality with other people who can understand it because they know the feeling of those abnormalities. The sense and feeling of community was just a byproduct of such interaction, whether intended or not. Because, without no one to talk to about these things, I would not understand such feelings and I will not know what to do with them. That's all.
