Basically, my friend and I were drinking, and then we went in my brothers car with his girlfriend who is also my friend, and his friend to go to a restaurant. As we were leaving, friend #1 starts throwing up. My brother then rushed us in the car, and sat me and friend #1 in the farthest back seat. After 40 mins I got confused, because it should’ve been a 20 minute drive and my friend was throwing up in my lap the whole ride, I had vomit all over my purse, wallet, and clothes. We pull into my brothers girlfriends house, who lives 50 minutes away from the restaurant. I texted my brothers girlfriend after she got out of the car, canceling our plans for the next day because I am so upset. She responded saying she would’ve been grounded for 2 weeks with no phone if she had been 15 minutes late, which is what it would’ve taken to drop me and my sick friend off at home. But instead they ended up driving about an hour and half with my friend covered in vomit, and me, so she could make it home not 15 minutes late. When I texted her she refused to apologize and got angry with me. I tried to explain myself but it was met with defensiveness, I have since ended our friendship out of feelings of betrayal, and anger. Am I the asshole?
