Didn't he gave you a deadline (what I am sorry, it's kind of weird)and it's not done yet? May be you can find a manner, not a chaseful one to bring him to your new counselor. Let him know you was not comfortable with the other one because you believe that you can find solutions and you want to stop the blaming game.
I think it would be also helpful to share how you felt "I think that he is angry and emotionally exhausted. All the feelings he has expressed to me are the same feelings I expressed to him when I moved out but with time I realized my contribution to the problems and that divorce is not something to take lightly because it doesn't solve anything."
But try not to sound desperate. Read through the posts here as there are great examples on this forum, of how you could carry this conversation. They were really helpful to me.
