Moving On - Season 1 Episode 3

Ellie has so many debts she is forced to put her house up for sale. The prospective buyer is John, the school bad boy, now a handsome and charming property developer who is happy to let her stay on as his tenant. They begin to fall for each other until Ellie's best friend, a married woman who recently had a fling with John and may be less than impartial, informs her that he has made his money not from houses but by illegal drug-dealing. He denies it and claims he loves her. Which of them is she to believe if she is to 'move on' and improve her situation?
