Paul - I think that you are doing a great job! You are going to have to communicate with your W. You have children and a shared business. There is no way that you can go NC.
I still talk to my H almost everyday. H reaches out to me way more than I reach out to him. I let him take the lead because I know that he is really only capable of reaching out when it is on his own time frame. It seemed like we were getting closer around the holidays, so I let my guard down a little. I sent my H two text/emails that were not able logistics and he did not responded to any of them. I just made a mental note not to reach out again and to continue on my journey.
I also recommend not venting to your friends about the situation. You need to process the emotions, but I think that you are safer talking about it to a therapist or just writing it down here or in an actual journal. I have yet to get good advice from anyone in real life. They all want me to feel better and think that if I just filed for D, all would magically be repaired. We all know that will not happen.
Your W asked for time and space. It is actually a gift for you as well. You don't need to make a decision today.
