Did anyone successfully shake off a similar perpetrator?
I've already posted mine.
I found playing at being cordial but breezy, telling her you're always on your way out or someplace to sever contact as soon as possible was the best strategy. Disinterested but respectful. The times I showed annoyance then she'd be back all the more sooner.
I think these type of psychos get off on unnerving you and trying to play mind games - it's a sport to them. They are trying to push buttons. As someone else said, it is a form of bullying / abuse, but just not what you'd expect from an adult woman. They want reactions. They want to see your fear. It's a power game. Intimidation.
I was frightened and you could say I didn't win, as ultimately I did move away - to great relief. Like you, I was also exhausted by it and the moment I stepped out of my house I was on guard (she'd always be there to intersect me on the way back home from work or back from the shops). This was long after I'd disconnected my doorbell to stop her from ringing it.
It really wouldn't surprise me if she's doing exactly the same now to someone else.
Stay strong and hopefully if you are not giving her what she wants she'll get bored and focus on someone else (I know that's an awful thing to say but that's the best you can hope for)... Don't play or let her know that she's getting to you. Avoid confrontation as she'll use it to start a feud and use it to maintain contact. That was the impression I got, that she was trying to push me to the edge so she could take it to the next level. At weekends she'd be in my face up to 3 times a day if I went out the flat.
The most funny thing was, a few weeks before I moved out I ran into her husband who said to me, 'Jill is really going to miss you because I know you two are good friends'. I was speechless... but then again she was always a good liar and she'd borrowed loads of stuff from me in the early days, or should I say 'coerced' would probably be nearer the truth.
