I HAVE A BEST FRIEND, I WANDER IF ITS GOOD
The girl could've been gossiping because she was jealous of your friendship or she wanted to be friends as well. She stopped, which is good. Whether you choose to be friends with her or not, you should always be kind to her. It's not nice of your friend to call her weird, it's just as bad for you guys to talk about her as it is for her to talk about you, so just be the better person and be kind. You guys could end up great friends.
