TIFU by mentioning to my friend the price of the tickets for a concert we would attend (before actually buying them)

A couple weeks ago I asked my friend (we're both 20) if she wanted to attend a kpop group's concert with me June next year. We like the group a lot and it's gonna be their first time in our country.

Today I decided to see if the tickets were already being sold, and to my surprise some of the options were already sold out, so I decided I had to buy them now. From the very beginning my idea was paying for both tickets.

I decided to confirm with her if she still wanted to go. She said yes, and said that she would pay me back later on, which I refused.

I ended up mentioning the price of the tickets (cheapest option being around $130 USD, (EDIT: Around $130 each) over half a month of minimum wage here), and she thought the price was too high. Now she no longer wants to go, even if I pay for the tickets.

She was willing to go, but after knowing the price she changed her mind. I should have just bought the tickets beforehand and given to her, I can't do this now, I don't wanna pressure her into going.

I'm still going to the concert, but alone, which sucks. I wanted to have this experience with her. We're planning to do something cheaper together soon though.

TL;DR I was planning going to a concert with my friend. She knew I would pay for both our tickets, but she changed her mind after I told her how expensive the tickets are. I should've bought them before.
