It would seem that the D will be cutting most ties. You will always have D6 as a connection.
I guess cutting all ties would mean, removing her things from my the house, Asking her to move out of the apartment once and for all, not contacting her for anything what so ever (other than where daughter is concerned). I guess that would be about it. Most of that would take place with the completion of the Divorce. I guess I could also hurry that along. I am not sure if ANY of those things will give me closure, or if I would only be adding conflict. I just don't know what to do. At this point, I am just letting the feelings wash over me when they come. I vent a little to my close friends, but I am trying to meet W with nothing other than calm reciprocation, bordering on distant. It is all business between us, and it normally only entails discussions directly regarding daughter. We are cordial, but not personal AT ALL. I have not asked her to join D and I for any activity since OM came into the picture. At daughters school events, we sit away from each other and don't interact. I have not included her in any personal conversations since OM, either.
Then Yesterday, she text me regarding a foster child she cared for. W provided child care for another couple during the day. At one point, W and I actually had a conversation about adopting her. That was about 3 1/2 years ago. Anyway, this girl contacted W, and it seems she was reaching out and asking for help. Her life is in a shambles, and she is currently a run away. Wife sent me several texts sharing her feelings and sadness. I validated a little and offered my empathy, but I did not engage her much. I left it fairly generic. That is the most personal conversation W and I have had in several months, and it simply entailed a few texts back and forth. That is where we are today.
