Liz, just know that all of his threats are just threats. He is not God or a judge, and neither was my ex.
I think you made a very good plan. You know how to be frugal. You may need that, you may not, but you are prepared.
I agree with you on don't say anything right now. You said he can get volatile. He very well may do that. It seems that he is trying all of this manipulation because of the lifestyle you are living now, and in his mind he can't believe that you will give that up. He might feel that he is one-up on you right now, but you know differently. In other words Liz, you are holding the cards, not him.
