Diary of an unsmug married

Meet Molly Bennett. Married to Max and mother to two warring teenagers, she's just 'celebrated' a significant birthday. Bridget Jones would call Molly a "smug married". So why doesn't she feel it? Is it because everyone seems to be having a better time of it than her? Or is it that Max has started showing more interest in 'business trips' and less interest in their sex life? Molly begins to despair. And then an old school friend starts flirting with her through Facebook.
