Fan, Michelle talks about a behavioral technique called "Thought-Stopping" in her DR book. It's brought-up in the context of helping those who've been betrayed by infidelity, not to obsess about it.
It's basically forcing yourself to counter the urge to snoop and to think of something more pleasant. With practice, it becomes easier to counter the urges.
I think the solution is going to involve practicing any type of countering technique--walking, writing, reading, changing the environment, meditation, etc...
