William and Kate eerily mirror the doomed marriage of Charles and Diana

Prince William and Kate Middleton, in an effort to fortify their union, have increasingly chosen to spend time apart.

The unintentional parallels between Prince William and Princess Kate's marriage and that of King Charles and Princess Diana have become more evident.

A source, speaking to In Touch, shed light on the growing divergence in William and Kate's engagements, attributing it to the princess's popularity among Britons.

Revealing a similarity with his father's resentment towards Diana's popularity, the future King harbors comparable sentiments towards his wife.

The insider disclosed, "He prefers solo events because Kate attracts all the spotlight when they're together."

Despite its subtlety, the future King's irritation at having the mother of three by his side becomes apparent during recent royal engagements.

From dismissive comments about her cooking to urging her with a 'chop-chop' at a summer wedding, or even outright ignoring her, as seen in a September podcast with Princess Anne where Kate struggled to speak, William's jealousy continues to surface.

Consequently, palace aides are diligently reshaping their schedule to accommodate "more and more separate engagements," allowing the royal couple to "cool off."

The insider emphasized the severity of the situation behind the scenes, painting a picture of discord within the palace walls.
