I don't really know whether she "knows" or not, however, during her stalking phase of me, she made up computer user names like, "anne.replay" for an e-mail address, and her divorce busting name is "replay" although she never made any posts with these names.
Her name here is "Divorce", since she registered here right after she filed.
So she did seem to be trying to send me a message I think.
So thinking about this, the pattern has been for her to use names based on the mental state that she was in at the time.
Maybe it was subliminal, IDK.
