I don't even live with my old flatmate any more, details of her antics are in here http://drownedinsound.com/community/boards/social/4346821
Anyway, I'm now safely relocated in a nice new house and I'm infinitely happier, however I recently found out my ex flatmate visited my old work (a coffee shop, not an office or anything) that I quit when I was still living with her, and started acting a bit fake (forced friendliness and chattiness) and asked questions about me as if we were still friends.
My old colleague said it was a bit unusual as she wasn't behaving as though she just happened to be in to order a coffee, instead it was more like she just wanted to come in and talk to all these people she doesn't know and has just seen a few times when she happened to visit me when I was still working there.
She also contacted a friend of mine a few months ago implying that I was going to speak to him about her in an angry manner and potentially in a way that was "bitching" instead of me sharing the truth, that she had gone slowly a bit...for lack of a better word, mad and scared me out of the flat.
I feel like going into my old place of work and contacting a friend (don't know if she's even contacted more people) and trying to make it seem as though I'm making things up....well, I feel it's a bit odd and I don't really know what to do about it. I wanted to just move on and forget she existed or that what had happened at the flat had ever happened but if she's contacting people who know me, who then tell me about it, well it becomes difficult to ignore.
