>>113508I appreciate your concern, nona.
But to be honest, if you push too hard, the situation could become dangerous for you. You have no way of knowing if this moid might decide to harm you for trying to advise his wife.
Unfortunately we can't save everyone.
My advice is this: if she brings up the subject with you, and asks you for advice, you can be honest, but other than that, you should avoid the situation. Please stay safe.
