There are two aspects to your questions about OG. 1) For you. What do you want/need to know to move ahead? You have to determine that. It is very difficult to listen too, so that is a personal decision that I don't think anyone here can tell you what to do
2) For her. Your W needs to deal with it. There is little emotion about it now, but that doesn't mean there won't be in the future. You seem to know very little about what went on, how she felt, how attached she was or wasn't. Probably a good things for her to work through with a C.
