THIS \/ \/ \/ Get the car description and license, and call the cops. If it is cops, they are blown and will leave (and try something else). If it is not cops, the cops will investigate and hopefully scare the crap out of the 'stalker'. And you don't have to tell cops you are ex, just a resident who has noticed this suspicious car/person watching the neighborhood . . . And get a big frickin' watch dog . . .
