Is it normal to not value any other type of relationships other than romantic?

Is it normal to not value any other type of relationships other than romantic? Like, what if someone has friends but doesn’t value them or like them at all? They don’t dislike them, but they’re apathetic toward everyone who isn’t their boyfriend or girlfriend and don’t care whether they live or die. They don’t care about their children or their well-being. Is there anything wrong with this?
