How can I ever move on from him?

Me and my ex dated for a year and 3 months. He was my first true love, first everything. he was so special to me. We were like twins, same interests, same everything. But he always tried to make me jealous with everything he did. he liked to copy me and through everything back in my face. He broke promises many times and he's untrustworthy. But i loved him anyways. I still think I love him. but last month, he had to move a few states away from me. It broke my heart, we had to break up. We had already broke up a few times, as in breaks and threats(So stupid) He texted me one day and told me he wasn't coming back ever because if his parents didn't find jobs, he was coming back. It crushed my heart and still does to this day. I'm having a hard time getting over him and I know i need to move on because he has. It's just so hard. My heart keeps thinking he'll be back for me some day and i'll have my happy ending. But he's not... I need to realize that. He even hurt me by saying a few weeks after he moved that he was seeing an older lady, and was going to move in with her, that she was so much better then me and all this stuff. it hurt worse. Sad thing is, every thursday, for 8 thursday's in a row, I cried. He always told me bad news on that day. Last week, i told him that we were better off not talking. All he ever did was hurt me more. i couldn't take it, talking to him. Butterflies? No... felt like i was dying inside. I'm having a hard time letting go and I'm scared to move on. He was my first love, nobody could be that special to me. Also, I miss talking to him. But i know we're truly better off not talking... My heart's torn and I don't know what to do about it. Does anyone have any advice or comforting words that might help?
