When Harrison Ford and his wife, screenwriter Melissa Mathison, announced last November that they were separating after 17 years to "work out our differences," the news -- coupled with Ford's appearance at several nightclubs -- baffled friends who knew the star as a scene-shunning homebody. Their suspicions now appear to have been correct, reports PEOPLE. Now the actor is back in a role he knows well: stay-at-home husband. Ford, 58, quietly reconciled with Mathison, 50, about two months ago. "They're definitely back together," a source close to Ford has told the magazine. "He seems happier." Even after he moved out of the New York City apartment he shared with Mathison and their children Malcolm, 14, and Georgia, 10, and into a hotel last fall, Ford never strayed far from his family, reports the magazine. He was around for every holiday and even stayed with the kids when Mathison went to L.A. on business in December. "When she came back," says one of Ford's relatives, "that's when they talked."
