A British woman has dumped her husband of four years after catching him having virtual sex with another man in the online world Second Life. Waking up in the middle of the night next to her husband John, Lisa Best looked over at her real-life mate's laptop to see his avatar, Troy Hammerthal, having "gay dungeon romps" with other male avatars.

"I just froze with my head on the pillow, silently watching what he was doing. I felt sick to my stomach," said Lisa Best. "After a few minutes, I could bear it no longer and sat up in bed demanding to know what the hell he was doing. He quickly folded the damn machine shut."

John Best doesn't think his dalliance was a big deal. He says he was just doing the dirty online "for a laugh," and denies being a homosexual (despite using the name "Troy Hammerthal" for his avatar). His wife saw things differently, and left him the next day.

This isn't the first marriage to be broken up by a Second Life affair. In November, we told you about another couple who split after the husband's avatar got a little too close to another lady on the site.
