Was I in the wrong?

My boyfriend and I broke up Saturday morning. We had planned to go to a show later that night before everything happened. I laid in bed for most of the day crying but then I decided I needed to get up just to show myself I could, that I didn’t have to lay in bed and feel sad. So I went to the show, part of me hoping someone would say something to me. I felt alone and wanted to get out of my head. I didn’t plan on going home with anyone, I just wanted someone to talk to. But even when someone approached me, it didn’t feel right talking to someone who wasn’t my guy. The next night the guy I had been dating asked if I wanted to come over to talk. And I did. We talked about everything and decided we wanted to continue seeing each other. He wanted to know what I had been up to the past couple of days and I told him the truth. But he thought I went out to go sleep with someone else and got upset. He kicked me out of his house and wouldn’t listen when I tried to explain. Now, he wants nothing to do with me. I can’t help but think that maybe I was wrong for going out in the first place but I also know that we weren’t together at that point. I don’t know.. what do you guys think?
