Is AUTHOR wrong in the post ? POST : So my college is taking our department on a tour of the nearby Coca cola plant. My best friend wanted me with her but I'm missing the tour as my ex will be there. Am I choosing not seeing my ex over spending time with my bestie? 

Both the girls are friendly to eachother but my ex hates my best friend because I used to spend more time with her.

Anyway.. so, AITA for blowing a trip with my friens so that I don't have to see my ex ?
