How long was the longest relationship?

Tery Fugate-Wilcox, artist, married 3rd day we met at 18 to Valerie Monroe Shakespeare, muse/wife, together literally 24/7/365/48years, every 25 million minutes. Married 3rd day we met at 18, never apart for anything for our entire married lives, only separated by death. Hard to believe, but the difference between fact/fiction is fiction must make sense. Life's too important to be taken seriously. Writing the auto-bio & hope to exchange stories with someone who may have lived the same way.
