This is one of the dumbest things anyone can do. All intimate relationships should have a foundation of friendship. Even if you're with someone you think is hot, even if you have sex all the time, for the times you don't, what else do you got? Do you enjoy talking to the person? Do you enjoy hobbies with the person? Can you solve issues with said person? If you don't have that, you don't have a relationship, you have a fuck buddy AT BEST.
I think because she lost her parents at a young age, she doesn't have the proper outlook on what an actual relationship is. She only knows that her father is white and that's what her husband should be; anything beyond that is outside her line of thinking it seems.
