Your best option is to consult a local attorney and make your divorce filing quicklly.
Under the rules governing the conduct of attorneys in New York it may be necessary to remind you that this answer could be considered attorney advertising.
I would change the pharmacy in which you have your prescription filled, make a police report stating that your vehicle is being used without your authorization, and call a local attorney to request an initial consultation. Many attorneys offer free initial consultations and some even accept payment plans with a significant payment up front to cover the initial filing fees and costs of preparation of the documents.
You may be able to start the divorce process, potentially get a temporary restraining order in place to help protect your reputation and your assets and make regular payments to the attorney helping you with your case. You cannot continue to do what you have been doing. You need to be proactive and start documenting every incident.
I wish you the best of luck!
