I feel awful!

Heather

So today at lunch, my friends and I were sat together and on our phones. My friend’s boyfriend put on his story a kiss emoji with just a black background. I was the first to see it and then told her but he then deleted it before anyone else could view it. For the rest of the afternoon she’s seemed pissed off. I asked if she was annoyed at me and she said no and I asked if her and her boyfriend were okay and she said yes but idk if she is pissed at me or not..help
