for my partner's case, he wants the experience of raising a human being that came from him and the person he loves. he admits that it's just that, and that it may be irrational, but he still wants it, anyway.
i don't think his inner child has been aborted or anything like that. he's a very happy person, the type who sings aloud in the car shamelessly, creates music, watches childish cartoon shows the likes of Barbie or whatnot with me, loves video games...
i wish i wanted a child as much as he did, but this is one thing i can't do for him, and he assures me it's fine, but it brings me guilt and a kind of sorrow to know that i'm robbing him the happy experiences he would get out of being a father. i used to be so proud and arrogant about my antinatalist views, but somedays now i wish i never opened my eyes. i--we--would be happier if i were a sheep.
