I'm angry because she went back on her promise to let me watch the house and see my dog while she was on this business trip.

That doesn't mean I still can't go over and see the dog while she is gone. It's still my house too. But it would have been nice to have her permission.

I agree that silence is my best option. Silence doesn't bother me. I prefer it. The truth is I would rather not communicate with her until she is ready to talk. I find talking to my wife stressful and non productive. We usually just end up in circles.

I will wait until she is ready to communicate with me. You are right. Eventually she calls. In the meantime I will work on the separation agreement and email it to her.
