Sorry to hear your husband is scammed, Naomi. Your case is not an exception - the scammer will destroy not only the life of the person they are playing with, but also the life of the ones close to the victim. They will try anything in their power to keep the victim away from anyone able to spoil their game. It will be not easy for you to convince your husband he is scammed - he is in denial and the scammer hooked him good enough to be more credible as any other real person around.
It might help if you can post here some of the details you have about that scammer - an email address and phone number/s the scammer is using, pictures your husband received (not nude or half nude pictures), some of the messages received - special the ones where the scammer is talking about "herself" or is asking for money.

what type of people are hidden behind those stolen pictures used in scams. With some luck (and enough details) maybe we will be able to show your husband the real face of his "love lady"...

;use it if you have doubts about someone met online. If someone met online only asks for money, no matter what reason, it´s 100% scam.
