trust your instincts. keep yourself safe. preserve your anonymity and distance. there is no reason you should reveal more personal details to someone else who won't reciprocate. even if they do give "facts" how do you know it is true?
i guess i'm a bit paranoid too.
There’s a special providence in the fall of a sparrow. If it be now, ’tis not to come. If it be not to come, it will be now. If it be not now, yet it will come—the readiness is all. - Hamlet, Act 5, sc 2
