Hi Sesame,
I'm afraid the answer to your question is maybe.
If you go ahead and re-add her to your contact list, block her and then delete her from your
contact list, and she's not online, she shouldn't receive a notification.
If she is online when you do this, then she should.
Also, this assumes everything is working correctly. Messenger add/remove contacts hasn't
been unreliable these past 8 months or so, so there really is no guarantee. Also with that
said, there is a small possibly you might still be on her allow or block list, in which case
she also wouldn't get the notification, even if she is online.
If you want my advice, I would just wait to see if she re-adds you, in which case, you can
just block her immediately from the "contact has added you" prompt. But if you really want
to go ahead, at least do it when you know she'll be asleep (which I suspect you probably are
more than aware of).
