ex is giving out my home address?

[Maria]

My ex from 2009 has been out to get me for a very long time. I called the police on him in 2009 for stalking, and he was arrested but let go because there was not enough evidence.

Since 2010 I have been receiving messages from a girl on facebook who said she "knows" I am behind certain messages she received (nothing to do with me, I have no idea who she is), and that she hired a private detective to get my ip address, and from that, she got my home address. It all went quiet in 2011 but has started up again since this summer - she even said my ex passed her my details and that he told her I was behind harassment she's been getting! I do not know this girl and have no idea what she's talking about.

I haven't acted yet as I have had an extremely bad year and don't have time for this girl and her games, I just blocked her on facebook. But I took a sneaky look at her facebook a few days ago and she and all her cronies were apparently planning some big "thing" where they are going to "get a certain someone" (the girl won't name me though but it's fairly obvious) - I took a screenshot of this, and then looked again just now and she's deleted it. I have made NO contact at all with her in any way, ever.

She says on her facebook "if a certain girl can see these posts, that just proves she stalks my facebook". Yes I do look at her facebook - to see what threats she's made this time!

She, through my ex's troublemaking, is totally convinced that I am behind whatever it is she's been "suffering". The only one suffering here is ME. Every time I hear a noise outside I think it's her or a friend of hers. My ex does know where I live and I can't just get up and move - what can I do to stop this?

I've collected a few screenshots but really don't want to go to the police as she'll deny she was talking about me, and she'll just make it worse for me.
