I'm Lucy, and I'd be happy to answer your questions today. I'm sorry to hear that this is happening.
Massachusetts does not recognize a cause of action for alienation of affection, so I'm afraid you cannot sue someone for trying to interfere in your relationship. But there are other causes of action here. Stalking falls within the purview of intentional infliction of emotional distress, as does most other harassment. That's an intentional tort, which means you're allowed to seek punitive damages on top of any other expenses. A death threat uttered to your face would be an assault, which is both a civil tort and a crime. But it also can be considered intentional infliction of emotional distress, and that will increase your punitive damages.
Lying about your reputation is defamation of character, which is a separate intentional tort, and also actionable. You're allowed to seek both compensatory damage for any money lost due to the lies and punitive damages.
If your losses are less than $25,000, you can bring your case in the District Court. For more than $25,000, you would be in Civil Court. You are allowed, but not required, to hire a lawyer to help you. Most lawyers who accept these types of cases work on contingency, which means you only pay after you receive a judgment. If you'd prefer to represent yourself, you can visit the law library in your area to look at books of forms that will help you draft the Complaint. Massachusetts has a great law library system, and the librarians are very helpful at finding what you need.
