Prince William and Kate Middleton are becoming more and more aware of the real test their marriage is going to face now that King Charles is slowly slipping away health wise.

Everything has been shared by a well placed insider that just spoke to Star

According to their findings the Windsor’s are currently concerned about the future and how it will effect their marriage in the years to come, considering “the workload and time required will quadruple,” once King Charles is no longer monarch.

Furthermore, they have already been called upon to take on more responsibility as is so “they have a very real idea of what awaits them,” the source added.

At the same time, “it’s not something they like to think about,” but still “Charles is aging,” they admitted.

What makes matters worse for his loved ones, particularly Prince William is that “he’s having health issues, and everyone is hyper-aware that William and Kate will have to replace him sooner rather than later.”

Moreover, “when that happens, it could be easy to become like ships passing in the night — but William and Kate are saying they won’t let that happen.” So “they’re being proactive to nurture their connection.”

For this they make sure to sneak away for “little weekend breaks while they still have the chance,” and they try to “keep it very hush-hush.”

Especially since “there are plenty of royal properties that can host them.” That is why “they can pop over to Scotland any time, which they intend to do early next year.” Also “a vacation in Mustique, with the kids, is also in the works,” the source also added before signing off.
