Trying, in answer to your question how long nc, I was nc for a couple weeks then I forwarded 2 emails tax related to her. At that point received several emails with questions I answered only twice and kept it short. She actually responded one more time with small talk about the taxes which I didnt acknowledge. But 9 days ago I sent a short have a geat day email which totally broke my nc. I wrote about it here. She never acknowledged and all has been quiet. Tomorrow 6th anniversary....
