What Was Eve Thinking?

We read in The Urantia Book that Eve defaulted only one hundred years after arriving on Urantia, after taking advice from the rebel Planetary Prince Caligastia. In celestial terms, one hundred years is a blink of an eye, and Adam and Eve had been warned not to follow Caligastia’s advice. 

Some have posited that she fell into his trap because she didn't have a Thought Adjuster. I disagree. These were supermaterial beings who came from Jerusem and who had existed for thousands of years (maybe millions) before being assigned to Urantia. They had received clear instructions to stay on the path that the Melchizedek receivers had laid out for them. We young evolutionary ascendant beings have Adjusters to guide us closer to God, but have no knowledge of the afterlife, of the administration and history of the universe, or of the number and types of celestials administrating the universe. We need the Adjusters to bring us closer to the God they had seen clearer manifestations of. 

In The Urantia Book we read the following:

“Adam and Eve had remained loyal to Michael during the Lucifer rebellion; nevertheless, the pair were called before the System Sovereign and his entire cabinet for examination and instruction. The details of Urantia affairs were fully presented; they were exhaustively instructed as to the plans to be pursued in accepting the responsibilities of rulership on such a strife-torn world. They were put under joint oaths of allegiance to the Most Highs of Edentia and to Michael of Salvington. And they were duly advised to regard themselves as subject to the Urantia corps of Melchizedek receivers until that governing body should see fit to relinquish rule on the world of their assignment.” (74:1.4)

Yet, they defaulted.

Solonia, the seraphic “voice in the Garden” who presented the narrative about Adam and Eve The Urantia Book, described her as lonely, despite the fact that she was busy with perhaps a hundred children and co-managing the Garden of Eden. 

“They were isolated, and the tremendous sense of loneliness which bore down upon them was all the more heightened by the early departure of the Melchizedek receivers. Only indirectly, by means of the angelic orders, could they communicate with any being off the planet. Slowly their courage weakened, their spirits drooped, and sometimes their faith almost faltered.” (75:1.4)

It's hard for me to believe that Eve was comforted by the wily eight billion year-old Lanonandek Son, when she knew he was a bad boy, and that, knowing what the repercussions would be, she thought mating with a Nodite prince would solve their problems (outside the Garden multiple “mating” was accepted (75:3.8)). 

What caused her to ditch the advice of the System Sovereigns and instead follow that of Caligastia, who had injured Urantia so greatly? Was it her impatience, her attraction to Cano, her spiritual weakness, like the sixty Nodites who went astray from the Prince's staff? Or some other defect in Eve’s make-up?
