Please stop assuming that Marie Antoinette did not love her husband, was trapped in a loveless marriage, or took a lover at any point during that marriage.
Please stop trying to further romanticize her life when it was already extremely eventful.
Marie Antoinette was very different from her husband Louis XVI, and yes, their marriage was arranged. But they were married when they were both young teenagers, which gave them plenty of time to become good friends and, ultimately, loving partners.
Marie Antoinette loved her husband.
Yes, she was a pretty, fashionable, charming social butterfly and yes, he was overweight and socially awkward, but they still loved each other–it was just that, a partnership.
And by the way, Marie Antoinette almost certainly did NOT have a lover.
Her life was tragic in many ways, but fortunately, a cruel, loveless, or unhappy marriage was not a burden that she had to bear.
Please stop buying into this common misconception just because you saw it in a movie.
ETA: There’s ample evidence that Louis also loved his wife.
