Oh yes, there is one more thing I forgot to mention. The timing of this all just happens to coincide with an event that could make him worry not just about me harming myself, but actually that I could get in a life threatening situation (something unrelated to our relationship) either unintentionally or by my own choice to participate. It's something we went through before together but he was there to protect me at that time. If the situation does get bad, he will have to face the fact that having two wives he can't be there for us both all the time. And this is a truth he needs to face. But by cutting off the calls, he just won't know where I am or what I am doing during that time and this will help to raise the anxiety that I could be in danger.
