On a scorching July afternoon, as the temperature creeps toward 118 degrees in a quiet suburb east of Phoenix, Ric Hoogestraat sits at his computer with the blinds drawn, smoking a cigarette. While his wife, Sue, watches television in the living room, Mr. Hoogestraat chats online with what appears on the screen to be a tall, slim redhead.

He's never met the woman outside of the computer world of Second Life, a well-chronicled digital fantasyland with more than eight million registered "residents" who get jobs, attend concerts and date other users. He's never so much as spoken to her on the telephone. But their relationship has taken on curiously real dimensions. They own two dogs, pay a mortgage together and spend hours shopping at the mall and taking long motorcycle rides. This May, when Mr. Hoogestraat, 53, needed real-life surgery, the redhead cheered him up with a private island that cost her $120,000 in the virtual world's currency, or about $480 in real-world dollars. Their bond is so strong that three months ago, Mr. Hoogestraat asked Janet Spielman, the 38-year-old Canadian woman who controls the redhead, to become his virtual wife.

he woman he's legally wed to is not amused. "It's really devastating," says Sue Hoogestraat, 58, an export agent for a shipping company, who has been married to Mr. Hoogestraat for seven months. "You try to talk to someone or bring them a drink, and they'll be having sex with a cartoon."
