I posted nasty things about somebody I was seeing online used his photos and cyber stalked him to find out what he was doing. Still have the compulsion to do it. He hurt me I did it to get revenge it didn't help. I think it's pain that hasn't been managed. Perhaps you didn't get closure. I still feel the need to know what hes up to. Truth is when I find out something I only want to know more and I end up getting hurt. But everyday it gets a little easier. I know there will come a time when I don't feel the need to know anything at all. sometimes it's hard to let go and accept how certain things ended not so much that they ended if that makes any sense. I certainly am not proud of my actions but pain manifests itself in different ways. The key I think is to find a way to move on and be at peace with oneself. Because trust me the ex's are just fine and not thinking about us lol
