Complex #4 - D talk started / Detaching continues

[Complex]

Quick question in between:
My mom is humongously worried, sad, angry and also very disappointed by WAW. Understandable. I always try to calm her and make her understand.
Until today I didn't know she wrote W an email 10 days ago, from what she told me it was on the nice as worried side. W never responded and is in absolute NC with my family. I guess that's normal!?

Now my mom wants to send W's aunt an email (very close family of W, the center of family, incredibly friendly ppl). I told her a few times its not a good idea and asked her not to do it which she respected. Now she asked over and over again, so I told her she can do whatever she likes, but I don't think its a good idea. My mom is a very considerate person and won't get personal or blame or so. Maybe deep down I'm hoping if she does it'll cause some family involvement...but I don't know if that's beneficial.
Any thoughts on that? Should I let her do what she wants or tell her not to do it and respect my and W's privacy????
