Growing up I lived on the same road as this girl, I’ll call her Gigi. For over 5 years off and on we played together and walked to school together. I say off and on cause we’d have a lot of fallings out over various things. Eventually when I was 13 I stopped talking to her altogether. I know I was 13 as the last straw was my birthday. The plan was 5 of us would go to the cinema and out for food. One by one all my friends cancelled on the day we were meeting for various reasons (Gigi said her sister stole her money, another was having a hair cut). Until there was one friend left. I was stood at the bus stop on the way to meet the one friend when Gigi and a boy walked past, laughing loudly about how I was still going to meet people and how stupid I was. It honestly didn’t click at the time. I went to town and stood there for over an hour, my final friend didn’t turn up nor did she answer her mobile or house phone. Then I remembered what Gigi had said. It has sounded like she knew there was no one to meet. I went home making sure that I didn’t go past Gigi’s house so she didn’t see me. Monday morning came, the girl who was getting her hair cut hadn’t had it cut. My friend who didn’t turn up gave me multiple excuses: slept at friends house, no alarm clock, not taken phone charger. (I mean we were meeting at 2 so how long did she sleep?) I said ok and went to sit with some other girls in my class. I never confronted any of the girls or Gigi, I never spoke to Gigi again and she never attempted to speak to me. Gigi ended up moving schools (but not houses). I heard from someone else because she claimed she was been bullied and the school was doing nothing to stop it ( she’d moved schools for this reason 2 times before). 
Many years later I’m at the bus stop, Gigi and her mum are there also. Gigi looks at me, I look away. She sits near the front so I have to walk past her to a seat. On the bus Gigi looks upset, is almost crying and her mum is saying loudly about how it’s ok, some people are just fake and immature and that Gigi is better than that. 

TLDR: am I the asshole for holding a grudge as she ruined my birthday,  ignoring the old friend and making her cry? 

holding a grudge for years which caused me to blank an old friend and made her cry
