Is AUTHOR wrong in the post ? POST : Hi, all!

I'm a girl and my best girl friend of the whole word is leaving the country to leave in Europe, she had a bon voyage party and my boyfriend made this big effort to go, because he does not like my friends at all. But he only stayed at the party for like 2 hours and then he needed to go home, I choose to stay to enjoy this last night out with my BFF. My boyfriend got really mad because he does not think it's right me for me to stay there while we came together to the party. I mean, he offer me to go by myselft several times and I did not accept and I was aware that he couldn't stay for a long time, but I wanna to enjoy the time with my friend and I did not know that he would do such a scene just because I was not coming home with him. Well, a big fat stayed at the party anyway and didn't even send him a message because I was so pissed. 

So Am I the asshole for chosing my friend over my boyfriend?
