“Even in the same State – if you’re self-employed – there is no garnishment!”
+1. I was going to point that out.
“Why is it needed to discus the divorce. It’s highly unlikely she will ever find out the truth, the husband will blame the wife and the ex will blame her husband.”
That’s why you have to try to speak to people who are relatively objective and not just the guy himself. Speaking to a Rav involved with the divorce is a good idea. And even if you will never know the complete truth, your hishtadlus is to ask reliable references.
If everyone you speak to tells you that he is a dangerous person and you should stay away, even though you have no way of knowing 100% that they are telling the truth and even though according to halacha you are not allowed to really believe it, you still have to stay FAR AWAY!
