As long as their is OM there is nothing to talk about. If she wants to drop the OM and work on the MR then you can talk but until then she gets nothing. She doesnt deserve to know your feelings. You have told her you don't want a D but if she wants to file you wont stand in her way. You have also told her there is nothing to discuss as long as there is OM. What more do you have to say? She is a big girl if she wants to file it is up to her.
If my W came to me and said she wanted a D I would do the same. Outside of not having sex for a bit I am doing great! I am sitting here on the coach drinking a beer in complete silence!!! After 16 years of having a W and kids in my ear I must admit it is quite nice .
