My response:
I agree with you. You should get rid of your husband as soon as possible. If he's threatening "Alienation of Affection" in MA, then he's just too dumb to be with you. You need someone smarter - - like an attorney!
Here's the law in MA:
(emphasis added)The General Laws of Massachusetts
PART II. REAL AND PERSONAL PROPERTY AND DOMESTIC RELATIONS
TITLE III. DOMESTIC RELATIONS
CHAPTER 207. MARRIAGE
ALIENATION OF AFFECTION AND CRIMINAL CONVERSATION NOT ACTIONABLE
Chapter 207: Section 47B. Alienation of affection and criminal conversation not actionable
Section 47B. Alienation of affection and criminal conversation shall not constitute an injury or wrong recognized by law, and no action, suit or proceeding shall be maintained therefor.
