<human>: A few months ago I split up with my boyfriend. I didn't realise until after how manipulative and emotionally abusive he was. He used to make me feel really guilty about things like sex or not travelling to see him often (we live a couple of hours away from each other and I didn't have a car). I ended the relationship and then he did something really bad. I'd rather not say what, but it pretty much tore me in half.
                          
After I ended it he kept trying to guilt me into getting back with him and even got his mother and others to contact me, telling me how I'd broken his heart and should make it up to him. I blocked and deleted him, his family and his friends and ended all contact. By that time I was so fed up with him and everything he'd put me through that that I had no problem with the idea of never seeing him again. Then I found out he'd been cheating on me pretty much the whole time we were together.
                           
That was back in June and since then I've had no regrets of ending the relationship, but I'm still so angry and hurt by what he did as well as the cheating. Because I found out he was cheating after I'd cut off contact I never got a chance to confront him about it, and I don't even know if he knows that I know. I want to be able to leave all this behind me and move on, but I can't seem to. I randomly stumbled across a picture of him tonight and I just started shaking so badly, crying and I felt so sick because I was just so angry.
            
I know that what I'm feeling is clearly very unhealthy, but I don't have anyone to talk to about it and get it all off my chest. I just need some advice as to how to leave this guy in the past and move on with my life.
