This long, "artsy" lifestyle, however, inevitably took its toll and the relationship between the two grew tense.

One night in Australia, Abramovic and Ulay, were awakened and found to be surrounded by hundreds of baby kangaroos. Abramovic recalled, "Looking at them, you feel like you are in heaven."

Following a prophetic dream, she ended romantic relations with Uray. They were born, like twin flames, on the same day, and their love, which had burned like a blazing heat, had waned to just flowing like a trickle that never runs dry.

At 10:47 am on March 30, 1988, Abramovic ascended the Shanhaiguan section of the Great Wall and set off from east to west, while Ulay did the same at the Jiayuguan section in Gansu province and traversed east. Ninety days later, the two met at Erlang Mountain, a rendezvous point shrouded with mystique, strewn with Taoist, Buddhist, and Confucian temples. There, they announced their breakup due to "differences in artistic concepts and life". After a total of 2,500 kilometers, the two's original marriage plan turned into a wave of farewell and their final cooperative work Great Wall Walk.

In the past two decades, the pair who have loved and abused each other, never ceased to be entangled, even in the form of a lawsuit against each other for the ownership of their common works.

In 2010, the New York Museum of Modern Art witnessed their reunion. While Abramovic was performing the work The Artist is Present, Ulay suddenly appeared and sat opposite her. Abramovic broke the rules, clasped his hands, and burst into tears. After dozen seconds, Ulay got up and left. And that falling of tears, once again, made the whole world realize the sincere emotion between the two.

"Everyone goes somewhere. It's not just me. Everyone ends up somewhere. Death is the ultimate answer. But life is absolute," Ulay once said.
