Discussion: Some help from the men

Guys I need some help. Please. Tell me what he is thinking. So here is the back story. I met this guy. We worked together. We hung out every night until the wee hours of the morning talking. Weeks went on like this. I was never really sure of his feelings. Then one night, I knew. We dated for a few months. Then he moved away and we continued to date for a few more months. Talking everyday, seeing eachother when we could. Well, then he met someone else and we broke up. We decided to stay friends. And we spoke and texted often. Well two months into his new relationship she broke up with him. We spoke more frequently after that and agreed to meet up. Well he leaves me a message one night to call him. I did, no response. Since then no text or voicemail or call has been answered. Why? I need to talk to him. Just one more time. Then I will leave him alone. Seriously. I will walk away. But the problem is getting him to talk to me. How do I do it? What can I do or say? What would make you return that call? Tell me what he is thinking. I do want him back. We were good together, we had this great passionate relationship. But I understand being away from him so long was hard. It was hard on me too. My job is taking me to the city where he lives. So distance will no longer be the problem. Which is why I think he isn’t talking to me right now. He doesn’t want to go through that again, but he doesn’t know about the move. Anyway. Someone tell me what to do.
