I don't understand how can one have a waifu and an IRL relationship at the same time. Don't you feel bad for cucking your 2d sweetheart? That despite all your love for them, you still surrendered to your own desires and got with someone else, emotionally hurting them?
Everytime I go to an waifuist community I see the exact same thing: all is love at first, but when the loneliness start wearing down they cop out of their committed relationship. Some get new "waifus", others seek to have more than one "waifu" at the same time, others even go for 3DPD, two timing their loved one. It's sick, it's degenerate self-centeredness. How would you feel if you were your loved one's husbando and them they decided "oh, I can't meet up with him in this lifetime, might as well hook up with a random pony".
And them are attwhores like >>42443515. Do you really think Pinkie would be happy with this bullshit? Value yourself. Think the opposite: what if she did something she regretted and decided to brand her own flank with another's pony cutie mark? Would you like seeing her with Cheese's on one side and Big Mac's on the other? It doesn't make any fucking sense.
And them, my friends, there this kind of bullshit right here:

>rather than my own Twilight being based on a character in the show, it's much more that the characters in Friendship is Magic were based on the same being that I am already in love with
Basically you don't love the character for who she is, but instead you use her to reach your ideal of a perfect partner. You don't want me meet her and know her deeply, you wish being the puppeteer of your own love, shaping her personality and memories onto something else. Sure, there is still part of the original character there, but ultimately you're the one defining how she should act and how she must feel. Waifus should be treated as POSSIBLE BEINGS, and not something to toy with.
