Talk to a lawyer about taking over the books and locking you out of the account. File a report with the police. You have every right to do so since he threatened you with physical harm. I don t think you ll be able to get a restraining order just yet, though, unless you have concrete proof of his threats (like a video of him threatening you). Get everything on record, keep any and all copies of emails, letters, phones and what-not you get from him regarding this matter. It ll benefit you in the long-run.So yes. Get in contact with a lawyer and the police ASAP.
kill him, sorry i have no idea but he seems like an @rs��hole ...
