I can relate to your obsessive desire to want to know what is going on from his side. Many years ago I had the misfortune of having a sociopath in my life. He lived with our family for 18 months and was destructive beyond words. When he finally left I was angry, felt completely betrayed, used and abused, etc, etc. I was seething with anger. One would think that once he was out of our life that would be that and that I would be relieved and thankful. Yes I was, but I was also obsessed with knowing where he was and how he was doing. I actually wanted to hear that he was in prison or something like that and in a sick and perverted sort of way it would have made me feel better to know that justice had prevailed. It took many months for me to stop thinking about him and now I rarely do. I still hear about his whereabouts from friends from time to time and I am still waiting to hear that the authorities have caught up with this lying con artist. You have a lot of anger inside of you which you need to process. He has betrayed you big time and it will take some time to get over it. In the meantime I think your feelings are completely normal so don't agonize over them too much. You wouldn't be normal if you could just switch off thinking about him since the experience has been a significant life event. Take it easy and take each day as it comes. As time goes on it will get easier.
