Are we over :(

I have even dating a guy for a month and a half and asked him to be my date to a friends wedding three weeks In advance. He told me he would like to go. I was nervous because I have been stood up before to a wedding, but he assured me he would go. He was working that weekend helping a friend excavate, but told me he set his own hours. The day of the wedding, he didnt call when he was supposed to. I waited an hour and then called him. He said he was still working, and would be done in 45 minutes or so. Time went by and he still wasn't checking in and I got really upset as the wedding was starting. I had been drinking and was slightly tipsy on top of being upset. i called him and texted him really upset for doing this to me. He told me he was still working, and that the rain had made it twice as hard. Needless to say, he never showed . this is where i admit i messed up. i texted him asking "how could he do this to me" and that i was really hurt and embarrassed , that I was sweet and how could he do this to me. I called him repeatedly, probably 20 times. I didn't talk to him the next day, but today I texted him and asked if he wanted to talk about it. He told me we had nothing to talk about and that I had been acting really childish. I told him that I apologize for my behavior, but that I was really hurt and embaressed in front of my friends, and that most women would feel that way being stood up to a wedding. He never responded. i waited about three days, then sent him a message that i apologize for my part amd my actions, i miss talking to him and that I have been really happy the past month. No response. I really like him, but am wondering what he is thinking. Does he not see how that was wrong on his behalf? Are we over? I understand my texting and calling was wrong and that I acted like a crazy person, but I feel like we both messed up and would just like to put it behind us and move on. How do I go about this, or did my actions cause irreparable harm.
