... . I began receiving silent hang up phone calls on my office telephone. The caller would just stay 
silent for a minute or so then i would here the click as the phone was hung up ... . 
I had exactly the same experience too.  Stalking like behaviour and I know for certain it was her. 
Never experienced anything like this in my life and coming from 47yo woman was downright disturbing. 
I'm so glad I got rid of her - best thing I ever did.  And so thankful the 'relationship' was very short lived. 
I just shake my head in disbelief sometimes. I seriously dodged a bullet with this one. Why do they do it? 
How long is a piece of string? 

  I guess its just their way of fulfilling a very sick need at the time.
In the end I eliminated all possible communication channels and that did the trick
