Leaning in to marriage, Sheryl Sandberg, Facebook COO and author of the motivational bestseller Lean In: Women, Work and the Will to Lead, has announced her engagement to strategic consultant Tom Bernthal. “You are my everything,” she wrote on Instagram. “I could not love you more.”

Sandberg was previously married to Dave Goldberg, founder and CEO of SurveyMonkey, who died suddenly in 2015. Her former brother-in-law, Rob Goldberg, introduced her to Bernthal last spring.

Before founding his consulting firm, Kelton Global, Bernthal worked for the Clinton administration and NBC News, where he won an Emmy award for his production work. Reportedly, Bernthal gave Sandberg an engagement band set with five diamonds, representing her two children and his three.
