Thanks for the replies. Yes I act completely cold hearted but i think he is worried that i might go to the police on accounts of something he did earlier on. I spoke to him last night (he showed up at about 11.30 pm) and told him that if he bothers me any more i will go to the police and report him. He seemed really deterred by that and went away but i still got an email this morning telling me about he thinks he has 'emotionally come to terms' and 'changed'. he wasn't asking for me to see him or for forgiveness or anything but it is almost as if he wants to keep updating me on his life and it bothers me.
