Questions: Break Up & Divorce

I was talking to this guy for about 3 weeks. He was all into me. Making time for me before and after work. Told me he couldn't believe he felt the way he did so soon. Then he tells me, he is spoiling me and has to stop giving me so much attention. After that I noticed a change. He wasn't trying to see me as much. He still texted and called, but it was always during his work hours, not after work. When I brought this to his attention he made an effort to change. During a conversation the topic of his children's mother came up. They seem like they get along so well(which is good) I asked him did he think they would get back together. He said maybe, he didn't know what the future held. That made me feel like maybe he was stringing me along, and maybe they are still involved. Here is where I messed up. I should have faded into the background, and dealt with him on a diff level. I told him it was best if we didn't talk anymore. We ended up getting into an argument via text, because he threw jabs and I threw back. I told him to loose my number and don't call. And he hasn't. Even after I apologized for not being "Christian like" (he had pointed that out in the text) He said some hurtful things, but I know he was upset for me telling him we should end it. I wish I hadn't told him to loose my number and not to call, because I do miss our conversations. Guys; Would you call back? From a guy's point of view what is he thinking? Part of me wants to call and tell him I didn't mean it and lets start over, but the other part of me keeps hearing him say, "It's my way, I write the book" and my head is saying "Don't you dare call him back, if he really cared he would reach out." What do you think?
