<human>: A friend of mine wanted to go to a show. She mentioned this in January. I had no particular interest for the performer, but I said sure thing, just for her benefit. About a month ago, said friend has decided to stop speaking with me entirely. I tried to reach out a few times and say supportive, encouraging things about her breakup (according to Facebook), and I never pushed her to tell me anything. I just lent her my support. She ignored all of my messages.

I paid her for the concert ticket in full, about 2 months ago. In fact, I just randomly remembered "oh yeah! That concert thing!" It's coming up in about a month and a bit.

Now, I don't want to attend this concert. Of course not; she's been ignoring me for a month for no reason and has made it pretty clear she's moved on, having fun with her friends (pictures on FB show this). I'm cool! If you wanna be my friend, great! If not, ok!

I couldn't attend even if I wanted to. Just got a full time job and I will be working.

So, I messaged her asking if she could please return my ticket so I can re-sell it, or if she would mind selling it to a friend of her's and giving me the money back -- that way she can still see the sold-out show.

It wasn't some sort of U2 Reunion tour in London that cost us $1,000/each. It's a 
small show! But it still is money, and I would like it back.

She hasn't replied to my message since yesterday. I will give it more time, of course.

If she does not reply, what do I do? I definitely don't want her to invite a friend/buddy and take them to the show, courtesy of my hard earned dollar. That would be unfair.

I have no physical proof that I paid her. No credit card statement, no nothing. She booked the tickets herself on her card. She knows I paid her, I know, and my boyfriend knows.

Summarize the given text in a few sentences.
<bot>: Friend stops talking to me randomly -- friendship is over. However, we were supposed to attend a concert together. I want either the ticket or the money back. She isn't replying.
