The heavy oak front door of our Austin estate groaned open, letting in a suffocating wave of July heat and the distinct, powdery scent of newborn infants.

My husband, Evan Rowan, walked in first. He wasn’t carrying his usual Italian leather briefcase. Instead, a canvas diaper bag was slung over his shoulder. A few steps behind him came his secretary, Leah Mason, her delicate arms wrapped around two sleeping baby boys wrapped in matching cream-colored cashmere blankets. Finally, my mother-in-law, Margaret Rowan, glided over the threshold. She moved with the serene, untouchable confidence of a monarch arriving for a coronation, rather than a woman coming to dismantle a twelve-year marriage.
