A message not meant for me....

For months me and my best friend (well we were best friends in high school and both started different colleges in September) have been planning to go to a scare house on Halloween, I offered to pay for her since it's close to her birthday and she was all up for it and said she was really excited.

Today in the morning I messaged her asking if she could pay halves on a taxi ride up there and she said it was fine and that she would even pay for the taxi by herself since I bought the tickets... I said I will still pay half.

Anyway. 30/40 minutes ago I get a message from her saying 'wtf (my name) is the one nagging me to go to this shitty Halloween thing and now she's expecting me to pay to get there! Wtfffff psycho'

I asked her who the message was meant for and she hasn't read it.

I honestly feel really hurt and confused. We didn't see eachother for almost the whole summer because she was busy and I was super excited to spend time for her. I'm thinking about taking someone else now..
