The situation was going to be known in the family sooner or later. If what you said was true and not done in the spirit of manipulation, I think it's okay. I have spoken to my 23 year old daughter about my marriage. The truth is the truth. Your son is an human being with his own mind and opinions. I think this is between father and son. Your husband will have a hard time successfully defending himself and maybe forced to look honestly at what he's doing.
