This is problem that should be addressed quickly and by an attorney. I would suggest you immediately seek proper legal advice by hiring a lawyer to protect your privacy. Your previous boyfriend’s threats, if any, may amount to the crime of extortion. Your future is at stake and any threat to it needs to be immediately addressed. I’ve seen a case like this settled for $100,000.00 where the tape was shown to a group of men for laughs and giggles. Obviously it was not so funny to the young lady. Although this is an invasion of privacy tort I've listed it under defamation, which isn't entirely accurate. It's an invastion of privacy case.
