Help😭

So I was talking to this guy for awhile and we were suppose to go to the movies tonight but I just messaged him today to make sure we were still going and he opened my snap chat and never replied and so then I message him on it and said " fine I guess we won't go then" and it's said pending so I don't know what to do we were fine 2 days ago and I don't know what happened or what to do and I'm so stressed
