Addictive and entertaining but frustrating and confusing ending. One minute Billie is watching her sons school play, the next she is running through the city to Brads apartment. Where did she tell Cooper she was going?, for a late night stroll for a few hours?, or 'put the kids to bed Cooper, just popping around Brads for sex.' Also, Cooper was tracking her on his phone app, but when we see her run down the street she has no phone on her. Someone explain. She makes it sound like its okay to cheat on your husband by 'wanting it all'. Hope she is full of guilt in season 2 after Cooper finds out and chucks her out.
