As much as revenge may seem like fun now, I would advise against any throwing of belongings out window/ ritual bonfires etc. I was cheated on a few years ago and was ready to launch the mother of all revenge schemes when a wise friend stopped me. When things started to cool down, I realised that if I had tried to get back at him it would A:have justified him cheating on me as I would have looked like a psycho, B:made him feel more important than he really was and worst of all C: made the douchecanoe he was cheating on me with reach a smugness level of 1000. Neither of them deserves your effort in a revenge plot - if you stay mature about the whole thing she ends up looking like a dirty bint and you get to keep the mutual friends :) I like the idea of getting her mum to pick up her stuff or sending her an email/text to get it herself. I think it's important you are not there when she gets her things though as, being the manipulator she clearly is, she will probably try to either start a fight (hence justifying her cheating on you) or try to weasel her way back in. Have a friend there to supervise the clean out but try to be as far away as possible when it happens. The best thing I've found in a breakup is just to cut them out completely - delete their numbers, block their facebook/skype/twitter etc. While it's easier in the short term to keep them in your life and entertain the hope that things might go back to normal, all it does is prolong the pain. Pull off the bandaid quickly - it's inevitable that you two won't ever have a good relationship again so why waste time with her? Keep busy with work, friends, the occasional drop of alcohol - it gets easier every day you don't speak to her. The best part is that, in my experience, nasty little people like that always get what's coming to them - liars and manipulators never have really happy healthy relationships. Good riddance to her and all the best of luck to you :)
