Did I over react?

I went out with a girl on Oct.4th. We we supposed to go out last night Oct. 8th she cancelled at the last min. and said I can't make it out until next week. Then tonight on Facebook she posted a picture of her and her friend at the bar we were supposed to go to. I confronted very calm and said oh you're out with blank tonight? She said yeah we went to the movies and then the bar. I said oh whatever. I think the least she could of done was cancel with her friend to make up for canceling last night. Do you guys think this is messed up or no? We made plans in advance on date 1. But last night she cancelled last minute. After I said my response no reply back from her. So she had time to do that but not to hang with me. We are LGBT by the way.
