It doesn't seem like talking to him in any way is productive right now.

I don't see the harm in cutting off all contact (if you think that is best and what you need)

Let him make the next move.

Just keep to absolute life or death communication...when YOU contact him.

That is kind of what I read from him "leave me alone!" from what you've put down here so....

My goal is to some day be the person my dog thinks I am
