A year ago, someone I was at school with made contact with me on Facebook. We went out for the evening and it was nice, but I heard nothing from him for a few months. He then said he was coming down (lives up north) so I invited him to a friend's birthday party but he didn't reply. He got back in contact with me in October time and we messaged quite a lot (via Facebook). I went up North to see him in December and things happened which I now regret (he didn't stay over with me in the hotel as he had to work the next day). The day before New Years Eve I found out (via Facebook!) he had been seeing someone else since October. He asked me twice to meet up again in February and March this year and has cancelled both times. If a friend had told me this about a bloke I'd be telling them what an idiot he is. So why can't I just do the same and move on?
