My high school best friend and I had been kinda drifting for a while, but the last straw was infuriating:

A mutual friend got married. On the way to the wedding, me and Mr.SmashedBrotato (Prior to us being Mr&Mrs) experienced complete car failure. I texted my then best friend, who immediately called and said she'd come pick us up, because she wasn't far away, and that it was no trouble. I gave her directions to the parking lot we were stranded in and we waited for 45 minutes, and she just never showed. Every call would ring once then go to voicemail.

We eventually had to call my Father-In-Law to come tow us home. I texted a friend who was in the wedding, asking if BestFriend had ever made it, and he said she was there and having a great time. When he went and asked why she didn't pick me up she walked away from him. I have no idea what I did or why she did this. If she hadn't wanted to pick me up, I could have done something about another ride.

Friend in the wedding told The Groom that our car had broken down and we wouldn't be making it. The Groom, who I'd been good friends with for years, called when he got the chance, to see if we were okay and ask what had happened. I said we waited for her to come pick us up, and he was completely baffled. He said he'd asked her where I was and she told him she had no idea.

I didn't even want to hear her reason why. I stopped responding to her texts and calls that day. There is no good reason for her to have volunteered to help us out, but then just leave us there.

The couple who got married that day don't really talk to her anymore, but they did give us one of the centerpieces.
