I know revenge isnt good, but had to laugh when my friend just told me what she did. She recently split up with her bloke, he was being a bit distant etc and she was becoming a bit bored. Anyway he made the mistake of giving out his FB password so she looked on there one night, she came across some messages between him and another girl to which she'd asked if he was seeing anyone and he had replied 'no she's just a work in progress' she dumped him after that. I asked her if she had ever had it out with him about it and she said no but she changed his password so he couldnt get into his FB. Laughed at that but then she said that didnt stop him for long as he just clicked on forgotten password and FB then emailed him his password which she'd changed to ihaveasmalldick ha ha ha ha
Was quite a subtle revenge, which I like, the fact she held her head up high not getting upset over him and chasing him or being a psycho, but still showed him she wasnt happy about it and wouldnt be treated that way.
