Hey there WLFTW,
You are in a situation that would make your blood boil and your sensibilities turn tail. Your wife is obviously in an abusive relationship but won't do anything about it. That has to be the msot frustrating and scary thing for you roght now and then there is that little fact of you loving her.
I think you need to buy a new SIM for your cell phone and call her from the number he doesn't have. If he answers ask for someone else that way she is safe. But she needs to talk seriously about how this man is treating her and what she wants for herself.
All I can do here is support you and hope that she comes to her senses calls the police and gets an order on him,
Rhiannon
