How do I redeem myself after breaking it off with my boyfriend?

I met this guy online, and we have been having a relationship through text, and phone. The attraction is "soul mate" like, and we talked about me going out to his state to meet him, and even marriage. Recently, I was upset over some things that have been building up, and out of anger broke it off with him over text. Afterwards, I regret the decision, and realized it was an over reaction, and misunderstanding, and have sent a few texts, and a phone call, but he's not responding. Basically I asked if we could talk, and told him I felt my decision was extreme. He did this another time to me when he got upset over a comment I made, and didn't talk to me for five weeks. It was minor, and wasn't worth being mad at me over for five weeks. He cures everything with sex, and the last time he didn't talk to me I had to send him explicit messages, and then he responds, and everything is fine again. I don't have a problem doing that, but asked him if that's what he wanted from me again, and he's not responding. I don't want to end it yet. It's a dominant/submissive relationship.
