Dr. Tammy Nelson, a sex and relationship expert, and Richard Zwicky explore how modern life is fundamentally changing the nature of committed relationships.

]Dr. Nelson, author of Open Monogamy, argues that traditional models are no longer applicable due to longer lifespans and a cultural shift toward processing emotions and trauma.

She emphasizes that commitment today is less about moral promises and more about integrity, transparency, and frequently "rebooting the mission" of the partnership.
