Boy/Girl Best Friends

Okay. So I have a guy best friend - we’ve been close for nearly a year now. His ex girlfriend HATED me, and now his current girlfriend hates me.

She acted like she liked me, even talked about lingerie ideas (oh yeah I have a boyfriend. My guy best friend set us up actually) and then two days after we had a double date she accuses me of talking behind her back, blocks me on all social media, and accused me of having a crush on my guy best friend. Ummmm no. He’s 3 years younger than me. He’s literally like my little brother. And did I mention I HAVE A BOYFRIEND. We’ve been together longer than they have! I just don’t get what I have done.

Am I the only one that thinks guys and girls can be best friends without anything sexual?
