Who was in the wrong?

Okay so my so called “best friend” and I are currently not talking at the moment and here’s why. So we were suppose to go on a trip for her bday and I asked her if it’s a girls trip to see if I could bring my bf and she said Nahh go ahead and bring him along. So cool, mind you I asked like 3 weeks prior to the lil trip and we were just suppose to be going to the beach at the time. So a couple days before the trip I learn that we’re taking a trip out the state and that we would have to pay money for the hotel and shit which is cool. My boyfriend didn’t mind paying or anything too so everything was all gravy until I learned that he would have no where to sleep. In our room it would be 5 people. 2 couples and a girl that was also my best friends friend. So basically my friend was trying to say that my boyfriend would have to sleep on the floor and I share the bed with the girl. PAUSE why would I not want to sleep beside my man? We were trying to find ways to work shit out but I just wasn’t having it plus the hotel didn’t have like a pull out couch or just a couch in general and it was just annoying. So my boyfriend and I decided to look at hotels but then I realized why am I the only fucking one looking for hotels and shit when everybody else got a bed and I just didn’t feel like it was fair to me being tho she been knew we was going so they could of planned a little bit better. So anyways I just decided that I wasn’t going to go. So I tell my best friend this and she told me to just leave my bf home and still come. I didn’t want to do that because one, you been told me he could come and two, We were already anticipating the trip and I feel like it would just be wrong of me to ditch him and just leave. Also why am i the only one that had to leave my boyfriend when she was still bringing hers. So we’re bickering back and forth through text message and she tried to question my loyalty to her and everything. I’ll post screen shots too. So my question is am I a bad friend for not going? And would I have been a bad girlfriend if I would have left my boyfriend? I just need more opinions.

EDIT!!!!

Okay let me clear up some things for people who aren’t quite understanding. So my best friend told me she wanted to go to the beach for her bday. I say okay cool is it a girls trip or what. She replies Nahh girl you can bring your man I’m bringing mine. Okay cool. 2 weeks later she texts and tells me the trip will be out of state still cool. Mind you 8 people are suppose to be going on the trip. 2 different rooms with 2 beds in each. Everything’s fine. 3 days prior to the trip a 9th person is added. Instead of that person having to sleep on the floor my boyfriend has to. I didn’t like that idea at all. We’re looking at hotels in the same building. Rooms are hella expensive that I don’t have the funds for. Looking at hotels around that hotel, realizes why the hell im looking for hotels when the 9th person should be. Decides not to go it’s not worth the headache. Gets called a bad friend for not leaving behind someone that she said could come. Now if I’m in the wrong or a bad friend for that then fuck it I don’t need friends 🤷🏾‍♀️
