Apparently she was a high roller hostess at a casino, met the high roller Paddock, and she left her husband for Paddock.

Ms. Danley was born in the Philippines, relatives said, and spent many years in Australia, where she became a citizen and worked for a time as a tour guide. She was married to a man who later died.At some point, she met Mr. Danley and moved to Memphis. The couple wed in 1990 and their marriage lasted 25 years.
Ms. Danley worked retail jobs, selling mostly clothing and jewelry. Both she and Mr. Danley had children from previous relationships. Ms. Waltrip was 20 when the couple got together; Ms. Danley has a daughter who now lives in California. The couple moved to Nevada when they retired.
They were extremely happy, Ms. Waltrip said. They loved each other very much.
But before the marriage ended, Ms. Danley met Mr. Paddock. She was working at a casino and he was a high-limit player, casino employees said. She worked there from 2010 to 2013, according to her LinkedIn account.
John Weinreich, an executive casino host at the Atlantis Casino Resort Spa at the time, said he believed that Ms. Danley frequently attended to Mr. Paddock, serving him food and pointing out which machines might be ripe for a payout.
When she was around, Mr. Weinreich said, Mr. Paddock did not seem to break from his intense gaming persona at all. Eventually, Ms. Danley became his regular host.
Then she was just gone one day, he said. I asked some fellow workers and they said she went off with Stephen.
She and Mr. Danley divorced in 2015. On the divorce papers, she listed her address as a condominium in Reno owned by Mr. Paddock.
You have good information. I am suspicious that Marilou became more than a high-limit hostess to entice the whales” to play poker.
