What should I do about my disgruntle friend?!?

My friend invited me to this awesome party. When we got there she went off to flirt with every woman and man in sight. I was having a great time and meeting new people when some "furries" walked in. I was a little surprised but everyone seemed to be fine with it so i struck up a conversation with one. I got interested in the whole furry subculture and did a little research. Since then I've hung with a few of my new furry friends as their human selves and their fursonas. I think its really interesting they all seem so nice but my friend called me an idiot for hanging out with them and becoming close with a few of them. She called me a furvert ,at a different party, which I didn't quiet understand was an insult (I know its really dumb to not have realized what that meant) until she got thrown out "for disturbing the tranquil and accepting environment". She has always been a good friend and very accepting but now that I've found something fun , but very different I'll admit, she seems a little less friendly. I don't want to lose my new friends but i don't want to lose her either. So what should i do?
