Given the rocky foundation, it’s no wonder the couple struggled throughout their relationship.

On top of those core issues, they had the added pressure of their royal duties and public scrutiny.

Despite often being unhappy together, Charles and Diana did their best to make the marriage work.

But as early as their engagement announcement, people began to notice uncomfortable interactions between them.

The couple often seemed stiff and nervous together.

On several occasions, Diana was visibly upset in front of the public.

Charles also made jokes, which only seemed to make the tension between them worse.

Talking about their engagement, Charles joked he was amazed Diana was brave enough to take him on.

The interviewer then said he assumed they were in love.

Even apart from that specific exchange, the entire interview felt stilted and awkward.

The young Diana was newly engaged and just getting used to royal life and all that came with it.

Diana saw him off at the airport and was seen crying as the plane took off.

Buta lot went wrong on Princess Diana’s wedding day.

While she looked lovely, she also appeared unsettled.

In many moments from the day, the couple seemed stiff together, and Diana appeared shy or scared.

He treated her very badly."

Years later,Princess Diana admitted she considered calling off the wedding.

I can’t do this.

This is absolutely unbelievable" (viaNational Geographic).

But after her family calmed her down, she decided to go through with the marriage.

Likely due to these misgivings, Diana appeared more nervous than joyous in the footage from her wedding day.

In his speech, Charles talked about his Australian tour a couple of years before.

“At that time, everybody was saying, ‘Good luck!’

and ‘Hope everything goes well!’

and ‘How lucky you are to be engaged to such a lovely lady.’

And my goodness, I was lucky enough to marry her,” Charles boasted.

At that point in his speech, there was an unexpected interruption as the crowd erupted in laughter.

This quip earned another laugh from the audience and from Diana herself.

At the time, it seemed like a happy and playful moment between the couple.

Her tears were obvious to anyone close enough to see her face, and a photographer captured the instant.

This created tension between the couple that built up to the moment Lennox snapped a photo of Diana crying.

Charles was looking away in the photo and didn’t seem to see his wife’s distress.

And I could have walked down the middle directing the operation."

This comment was made in reference to how popular his wife was while they were on the tour together.

The audience laughed, but when the camera cut to Diana, she was looking down and seemed uncomfortable.

Years later, the princess revealed how difficult her popularity had been for Charles.

The moment is even more tense watching it today.

She gained widespread attention once again while on an official visit to the United States with King Charles.

During the 1985 visit to the White House, Diana danced with “Grease” star John Travolta.

Diana was seen smiling as the actor twirled her around in a beautiful black evening gown.

Unfortunately, that attention may have rubbed her husband the wrong way.

This frustration led to another awkward public moment between the royal couple.

Diana and Charles spoke openly throughout the interview and seemed to have true lighthearted moments.

However, there was still some tension.

One tense moment came when the interviewer asked them about an apparent disagreement they had while skiing.

Charles answered that they do occasionally, but Diana remained insistent that they didn’t fight.

But today it makes me feel terribly sad."

Watching the moment back made many viewers sad for the couple.

One commenter wrote, “you might even tell how out of love she was becoming.”

However, James pointed out that they had PDA moments in earlier years that were much more passionate.

This contrast between their early kisses only makes the 1992 moment all the more uncomfortable to watch.

As their marriage floundered, the couple seemed to have a hard time pretending things were fine.

Eventually, Charles and Diana’s marital troubles reached a boiling point in 1992.

Their divorce wasn’t finalized until 1996, a final blow whichDiana’s private secretary says still affects Charles.
