"I know that Harry has had a lot of counselling in the wake of his mother’s death, and I hope that they have the support around them to guide them through the next stage," she said.
According to Mollard, the Duchess hinted at their relationship struggles in the past, saying:
"We have the fairytale, with the first tour, and everyone swept up in Meghan and Harry.
"We know from what Meghan said at the Lion King premiere when she was talking to Pharrell Williams, when he commented on their relationship and how much of an inspiration they are.
"She was heard to say, ‘They don’t make it easy’.
"Now, we don’t know who she means by ‘they’, does she mean the public, the media?
"But, there was a first acknowledgement ever there, that it is hard, and it is challenging for them."
She concluded: "The reason I think it’s the make-or-break time, as I say, they’re at the three-year point in their relationship, they’ve had a new baby which is a pressure in itself, and they’re in this invidious position where they are Royal, but not-Royal, having ordinary lives.
"I’m hopeful, but I don’t think it’s going to be easy. It’s hard enough for ordinary people."
