"The Young and the Restless" recap

Last week, while Phyllis was ranting to Jack about Luca, she got distracted by Bethany and Billy’s presence. Things got awkward when the four of them decided to share a table. Bethany asked Phyllis and Jack about their marriage, to which Jack answered that they’ve survived difficult times. When Bethany revealed that Billy’s dating her to take his mind off the love his life, Billy pulled her away and took her home. Once alone, Billy lashed at Bethany for being too cocky. She assured him that Jack did not suspect anything. Phyllis then appeared on Billy’s doorstep and paid Bethany to go away. Billy and Phyllis talked about their problem, and he said they can’t pretend anymore. “We love each other,” Billy told her. However, Phyllis said she can’t leave Jack and ruin their family. Billy suggested telling Jack the truth. “We tell him now.”
