I'm angry at my friend after she ditched me for a date
Maybe she wanted to spend time alone with her date
I felt like I was getting ignored and that my friend didn't consider me as a friend.
I understand being upset at a friend that cancelled on you. People should be considerate of others when making plans.
I don't care.
Have you talked to her about how her behavior made you feel? If you share how her behavior affected you then it will be more likely that she won't do the same thing again in the future.
