My breakup and coping

I was in a two year relationship with the boy of my dreams, I admit it was unhealthy because I wasn't doing my part. I told him I'd change, but by that time it was too late. His parents always had problems and he was the one solving them, and his dad was a jerk to him. He changed to the worst, I broke up with him hoping he'd change and come back, since we were head over heels for each other. We fought a lot, yet we always found our way back to each other. I truly loved him and I still want him back, his friends told me when he wanted me back during our breakup, and would get drunk and cry because he said he lost me. I was so depressed, I had no one, my friends were so unsupportive of him. It made me feel even worse, I tried everything, I mean everything to take away my depression, i cut off communication with him cause everyone says it helps in moving on, I honestly feel so much worse. I texted him before yesterday but he takes half a day to reply. I miss him and love him so much. I'm trying to like other guys I swear I can't. He's always in my mind. I feel and care for him so much. I just want him back... I feel like I'm the only one feeling this way, he moved on... I'm so broken.
