Following their reconciliation, John Lennon and Yoko Ono enjoyed seven more happy years of marriage. Following Lennon's death in 1980, Ono was understandably distraught about the loss of her husband. In a 1990 interview with New York Daily News, Ono said of the time following the loss of her husband, "After John died. Some days, it just wasn't that important for me to go on," according to Newsweek. Their son, Sean, kept her going through the hard days, and in the same interview she shared, "As a mother I told myself, 'I gotta survive.'"

Though Ono never remarried following Lennon's death, she did have a long-term relationship with Sam Havadtoy, an antiques shop employee, spanning decades from 1980 to 2000 (via The New York Times). Not much is known of the relationship between Ono and her much-younger beau.

As of writing, Ono still lives in the same apartment that she shared with Lennon – the site of his grisly murder. She has thrown herself into art over the years, and continues to pay tribute to Lennon regularly.
