Over the course of Series 3 the three friends have to face up to some big questions: what's the difference between having sex with someone and going out with them? Is it possible to be happy for your little brother when he gets married before you? And what's so sexy about MILFs anyway?
Series 4 finds Meg in a new relationship but it's not all plain sailing. Her new boyfriend Andrew might seem perfect but they've now been on four dates and he is still refusing to have sex with her. Meg takes the advice of her friends and adopts a number of strategies to lure him into bed.
