I don't think your delaying your reply will come off as your are angry. It will be your reply. If she texts you and your replyvis not feel with anger or contempt I think you will be find.
IMO, I think delaying your reply reminds her, she's not your top priority, and you have a life.
She just cancelled on you, showing you that you are not her top priority and she still have a life besides you. So I wouldn't let delaying your reply bother you too much about how should will read it.
