What could be more humiliating than meeting your ex on your fortieth birthday? And what if it’s the ex you left two months ago, because even after ten years together he wasn’t ready to marry and have children? And what if the ex came to a gender party with his own wife? And she clearly doesn’t have a two-month pregnancy! I would love to whine that my life collapsed—but there’s no time. I urgently need to make him regret it!
