As I said yesterday I agree with Taz when she says that they are not together, that they only come together for business ventures and that they are not loved up as they like to display. It is especially noticeable when they argue because when they do you can clearly see that they cannot stand the sight of one another.
And I always always always distrust people who try to show off how much they are 'in lurve' by clutching onto each other constantly.
I worked with a guy years ago, he and his wife would make you uncomfortable to be near them on a night out with their slobbering. He was well known to have cheated on her, more than once.
Also when you see any of the royal couples W&K, or C&C, or E&S, there's just harmony between them, in public. At ease in one other's company, no need for slobbering and pawing to prove anything.
I'd say at this stage H&M deeply dislike, if not indeed hate one another.
