I accidentally stood up a girl...now she won't talk to me.

I had plans to meet with this girl I met the previous day for a drink.Beforehand my friends and I drank a lot of popped some pills. To make a long story short, I went to the wrong place we were to meet and inadvertently sent one or two mean text messages. When I explained this to her the next day and profusely apologized I heard nothing back at all.

She was bringing a friend with her and probably took a long time to get ready. I can tell she really liked me. I screwed up and want to know why I am getting the silent treatment even though I apologized.
