Getting Back Together With An Ex

My ex and I were together for almost four years. I met him when I was 17. I dated him all throughout nursing school, and then when I graduated, we moved into together. We broke up two months later. The reason we broke up is because the intimacy in our relationship disappeared. And he also started drinking a lot. Alcoholism runs in his family. He was never violent or dangerous when he drank, just extremely annoying. I think that I got bored with the relationship because of how young and committed I was, so I moved out and we went separate ways. I was single for two months, then dated some guy in the army for a few months who ended up cheating on me. Yay. Here I am, single again, just working on myself and spending time with friends and I recently hung out with my ex since we were the best of friends. I missed him a lot. We've had a great time when we were together but the whole flame disappeared and it was almost like we were just friends. =/ I really care about him and I enjoy spending time with him again. I just don't know if he and I should try dating again eventually. Has anyone ever experienced this or tried this?
