Yes,you are correct, its only slander if its untrue. And guess what, its untrue. Every thing in this comment referenced is untrue, not to mention, ridiculously immature. And , the person making those comments can be sued. But you did use the correct word "story", because thats all it is, fiction.
Ive known my ex husband for almost 13 years. He would never, EVER steal money from anybody nor behave in the manner in which the story portrays him.
Watch your step not so anonymous one. You are dreading on litigious waters.
