...but I need advice if I should call the police or just stay quiet and contact a lawyer.
Hi Alessandro. I hate to hear about your troubles. It sounds agonizing. I think in a way you sort of answered your own question -- it's the type of thing a lawyer would need to answer, so yes, I would say to call one. Laws vary a lot by location and it sounds like you need guidance from someone that can tell you the right thing to do for wherever you are.
