Such a Pretty Lie (2014)

A 40-something comic-book writer falls in love with a dermatologist. It's a passionate romance, and he wants a baby right away. The trouble is, Christine gambled on her youthful looks to lie to him about her age. She's not 42, as she said, but 50, an age of physiological upheavals for a woman. Trapped in her lie, she finds herself spending the weekend at a family party, where Bruno's mother calls the shots. Christine would like to tell the truth. But the presence of Bruno's ex-wife, the announcement of "their" daughter's engagement and the step-family's arrival plunge her into a whirlwind she didn't ask for.
