I noticed that you really didn't answer her question about why you don't want the Divorce...
This struck me also. It reads like you held off on the divorce because you were letting her insurance continue rather than because you dont want to push for a divorce you dont want.
I think you did good not going down her rabbit holes, but Id say, instead of ignoring her questions, it may be best in the future to give small, concise snippets of things. The things Mach suggested are great examples.
