I need to anonymously tell the wife of an abusive and chronically unfaithful man that he is unfaithful to her.
I presume she knows about the abuse, as it happens to her, but from conversations with her I feel that confirmation of the infidelity will be the thing that will set her free and finally give her a reason to leave.
I have no vested interest in her knowing (I am not the OW,) I am actually related to her H, so see first hand what goes on and am privy to family discussions about it all. The rest of the family protects him and tells him just to divorce her when their DC are over and I find that very unfair.
If it was revealed that it was me who told her then my family would shun me and consider me completely disloyal.
Which comes to your advice. How do I do it in the most anonymous way possible? A way where even if she showed her H and he employed a whole technology investigations team to trace the message it wouldn't get back to me?
