Some of the choices seem a bit weird to be honest. For instance if Ian is dating Lena, he feels quite ok about cheating on her with Cindy, but apparently having a threesome with Jeremy and Alison is not ok. And there's the threesome between Lena, Louise and Jeremy, which apparently isn't classed as cheating ( if Lena and Ian are dating). I also don't understand the logic of Ian being able to cheat with Cindy and later Alison, but not with Emma. Lena has to stop having sex with Robert because Ian despises him, and knows they've been hooking up. But Lena is clueless about Emma. So why is it ok for Ian to continue fucking Cindy and Alison, that Lena suspects has been or might still be involved with him, but the person she's totally unaware of, somehow she's completely out of bounds?
