So I am a 22F and I am in a close nit church community. Ive danced at church for years. I currently dance with a group of girls who are 25,20,18,& 17 years old. This Sunday (yesterday) I received a text from one girl who doesn't dictate when we dance at 9:10 AM saying that we would be dancing that morning at 10:00 AM. When she texted she also did not include the song that we would be dancing to. Usually we would pre-plan this at least a week ahead so everyone could have time to practice. I did not see the text until right before service started. After church I approached the two older girls who danced lets call them mary(20 y/o) & ann(18 y/o) about them texting last minute about dancing. I explained that I was upset and angry with them that they planned this so last minute that it resulted in me not dancing. I asked to see text messages trying to pin point when this was decided & told them going forth to decide a week before if we would be dancing so everyone could be prepared. After this conversation I left church and I heard that they had been crying about the conversation. Hours later their mom calls me, I didn't pick up the phone because i felt as if she wanted to talk about the situation and say that I was in the wrong. I also didn't answer because they are both in college why is their mom calling? However this has caused the entire group to go to shit. I believe that i didn't say anything wrong, I asked questions, explained how i felt & even provided a solution. I am also very upset because I am pregnant and that most likely would have been my last time dancing with them. They dont know that so I dont hold that against them because they dont know but i just feel like their poor planning resulted in me being left out. Am i the asshole here??? Should i call their mom back?
