Is it normal that i can't stand this person anymore?

So I really wanted to go on a little road trip with a friend out of the city and she said she would bring a visitor from overseas to show him around. I barely go on any trips and I thought overall it was a great idea seeing as they both can't drive they would not have been able to get out of town. On the way there it became extremely awkward for the hour long trip and I tried to make conversation but they both would not talk to me. When we got to the destination, and tried to go partying, the guy ran off and we couldn't find him. Anywho later in the night after my friend was drunk I found out how a couple days before her and that guy had fucked and now it is awkward between them but I couldn't care less because I don't know him that well. After that situation my friend became awkward with me and barely talked so I decided to do the same back and since then we haven't talked. Also she had a whole bunch of my stuff returned it to me defective and not even offering to fix it until I brought it up. The sad thing is we used to be really close and now those situations really pissed me off. The hard thing is I'm in a situation where I have to see this person everyday...and it still bothers me to even look at them sometimes
