AITAH for being mad at my “friend” for screwing me over, wasting $300 of my own money, and leaving during a 3-day concert

I’m beyond pissed so I apologize if this post makes little to no sense.

I’ll try to keep this post as vaguely as possible, as I don’t want my “friend” or her partner seeing this post and making the situation more worse.

“Death by a thousand cuts” is the perfect phrase for me right now as that’s how I feel.

My friend wanted to attend this festival so she could see her favorite artist. I already had a problem with this from the rip because one day she casually mentioned to me we’re going to this festival and she bought my ticket already. Didn’t appreciate that as I felt forced to go, but didn’t push on it as I know this was her favorite artist. She informed me during that time that I won’t have to pay her back as long as I can secure the hotel/airbnb. I didn’t have an issue with that and booked an airbnb for like $250 or so.

The festival starts this weekend and my friend arrive at the event. Just for context, my friend is plus sized and has some difficulty with walking long distances. I knew from the jump this was going to be a barrier as we had to walk a significant way from the parking lot, to the actual festival, and on top of having to walk pretty far to get food, water, and to use the bathroom while in the festival. My friend was pretty… fatigued out by the time we found a spot and just wanted to stay there for the event. Not a problem until she kind of treats me like a caretaker where she’ll ask me to grab her stuff when I get something. For example, I went to go buy merch and she asked me to get her food and water. I was annoyed because those are in two complete different directions (very far apart) so I had to walk and wait in 2 additional lines for 40-50 minutes that I missed one of the artists I wanted to see. STILL- I kept it leveled until the end of the night when shit went south.

We had to head back to our bus as they were finishing up for the night. We left the festival at 10:50, the bus stops running at midnight, the bus stop is across the street… why did we not get on the fucking bus until fucking midnight and almost got stranded. The reason it took so long was due to my friend having to take multiple breaks to catch her breath to the point she told me just to walk infront of her and get ahead. I still stayed with her to ensure she was fine but walked a few distances at little check marks to make sure I still had eye view. As a result, this took an additional 30-40 mins where thank god we got on the second to last bus for the night. But i was very mad at this point as I got to the bus stop at 11:17 and had to wait for her as we had to walk through this weird line to not overwhelm the busses (I know this is a poor description, I’m sorry). By 11:45, I’m still waiting for her and noticed she’s taking another break while in the bus line. I nicely told her if she could keep walking as I heard the bus driver state that they only had a few busses left and anyone who didn’t get on are SOL. She fucking snapped at me like I was attacking her and didn’t talk to me for the rest of the night once we got on the bus. Making me feel like I’m bullying her when all I’m genuinely trying to do is make sure we’re both safe and not stuck in the middle of nowhere at 1AM.

When we got to the Airbnb I noticed she was outside and on the phone and knew she was chatting with her partner. Well, this morning, I was so graciously woken up by her by having the door be slammed open, her telling me I was being rude, she’s going back home, and her partner will be picking her up. At this point I snapped at her and she kept saying “I don’t wanna fight”. ??? - I’m sorry, you just woke me up to this complete bullshit, I’m out of $300 fucking dollars, have to drive back home (thank fucking god I took my car), and I’m the bad guy??? She kept saying her feet are cramping and she’s in a lot of pain and not taking her feelings into consideration (which is funny because she clearly doesn’t give a fuck about my feelings). I’m not ignoring that and understand but the way she went about it and now isn’t talking to me like this was my fucking fault??

So I’m home now, still fucking pissed after taking a deep nap, and just feeling super fucked over. I’m really fucking sad not because of this, but the fact this is my only friend left. I feel like there’s no point in having this friendship as I don’t think I can really get over this situation. My brother mentioned to me before that growing up you lose a lot of your childhood friends and this just makes me so sad because he’s been accurate so far. So I’m just dealing with a lot.. I just feel… pissed. Sorry again for any typo/grammar issues as I’m typing this on my phone and still pretty pissed
