“Significantly, romantic friendships can coexist with the fact of partners' marrying because their reason for being is not to replace marriage but to open the possibility of sustained, committed true love existing among friends, and not just same-sex friends. No matter that our chosen relationship commitments change. Those of us who have long-term romantic friendships, some that have lasted longer than any of our marriages or partnerships, do not fear that these commitments will falter if we create primary bonds.”
