Ex boyfriend.

I am still in love with my ex boyfriend, we were with eachother for 4 years.. But it ended badly (about 3 weeks ago) he had to move away. he never came to say goodbye and explain why. Which I resent him for and have not cried since it happened as I feel he didnt love me as I loved him,,how could he when he just left? He said he thought I didnt want to see him when I told him what time to come over…it makes me angry that he just left its making me think did I really mean that much to him. Anyway I’ve been having dreams about him a lot lately like of him with other girls and also him saying hes sorry. And its really getting to me, I miss him love him. But hate him for leading me on and being such a coward about the whole situation. Please guys I need some advice its starting to get to me big time. Im 18 and I know I will find someone else but he was my first love. I’ve been trying to put it at the back of my mind for weeks since he left but I cant ignore it anymore. Cause I know deep down he didnt love me towards the end. And it really hurts to think that hes moving on and replacing me so easily when im left behind still picking up the pieces of my heart from him once again.
