He didn't respond to my apology?

The guy I've been dating now for over 2 months and I went out last night. He wanted to go somewhere that I really wasn't a fan of and suggested we see a movie instead. Then he said he was really wanting to go to the place he suggested and so we could just hang out tomorrow night instead. I got a little upset because this isn't the first time he's cancelled on me for not wanting to do what he wanted. Though the last time it was because he thought I wasn't serious about him (he asked me to spend the night with him), which I turned down because I thought he wasn't serious about me. We talked about this a few days later and realized how stupid we were. After he said that we should reschedule last night, I overreacted, got upset, and ended up telling him that we could do whatever he wanted to do. So we went, but I was in a bad mood all night and he definitely picked up on it. Things went alright though after that and when I woke up this morning and had some time to think about what happened, I figured I owed him an apology. So I texted him and haven't received a reply. It's been almost 2 hours and he rarely keeps me waiting that long. Did I screw up? Was I right in respect to needing to apologize to him? What could he possibly be thinking of me? I feel so incredibly vulnerable right now. I'm just not good at expressing myself. Help!
