White boyfriend mixed race women

jada

So last night I was having a big talk with my partner and I’m dead set that he’s he guy I’m going to marry and have children with, without getting ahead of ourselves and he feels the same, we were have a general conversation about children last night and he made a comment saying “ I know this sounds horrible but I want white kids.” I’m a mixed race women dad being black and my mum being quarter black but mostly white, to me this was something I was shocked by but I understand how people have preferences, I don’t know what to think or say or if I should just ignore this comment, ADVICE PLEASE
