Hello. My name is Alex.
Thank you for your question.
I will be happy to provide you with information you are seeking for educational purposes only.
Unfortunately, generally, if the assault was reported to the police, the police report would be made confidential while criminal investigation is being conducted and would not be available to public, including the alleged suspect, unless criminal charges are filed against the suspect.
Also, if one adult person does not want to talk to her adult ex, not only such adult cannot be forced to talk to anyone, but it would be a good idea not to contact an ex, who doesn't wish to communicate, since unwanted contact can also result in potential harassment and / or stalking charges.
I am very sorry to provide you with this bad news, but please understand that I do have professional obligation to provide JustAnswer.com customers with correct answers, even when answer is not favorable to the customer.
I wish you the best of luck and God bless you!
