Eish good luck bro, I caught my ex ex ex GF like that, not with skype tho but with MIRC, I set my IRC up to save LOGS for all convos, to make matters a bit weirder I saw her deleting the logs (shift DELETE) and because I knew that she had to 'HIDE' something I ran Get Data Back and Recovered the logs, you shoulda seen the messages I recovered...."I'm in love with you, nice seeing you the other day, etc etc" I showed her this and because it was like midnight I told her to pack her bags in the mean time, because tomorrow first thing YOU'RE OUT!, and I stuck with it, booted her out early the next day...
