Hultberg was first married to Hilary Blech. In 1961 Hultberg met fellow artist Lynne Mapp Drexler at The Artist's Club in New York. Artists there discussed abstract expressionism. Drexler and Hultberg were married and three years traveled and lived in Mexico, the West Coast and Hawaii. Then, they lived at New York's Chelsea Hotel in the late 1960s. Seeking a relaxing environment, the couple bought a house off the coast of Maine on Monhegan Island in 1971 and split their time between New York City and Maine, particularly spending the summers at their island house. By 1983, Drexler moved year-around and permanently near Lighthouse Hill on Monhegan Island, an artists' haven off the coast of Maine, where she had spent most summers since 1963. Hultberg did not like to live year-round, particularly during the harsh winters, at Monhegan Island and moved to Portland in 1985. He asked Drexler to come with him, but she decided to stay on the island. They were estranged at that time of her death, on December 30, 1999. He died of complications of a stroke on April 15, 2005, at Roosevelt Hospital in New York. He lived on the Upper West Side of the city. He had a son named Carl R. Hultberg and Elaine Wechsler was his agent and partner.
