So a few months ago one of my best friends had me meet one of hers. At first we all got along really well. It was the tree of us. But as time went on I realized the girl was toxic, selfish, and a liar. I want to cut her off but I don’t know how. I don’t want to get my best friend in the middle of it. But this girl brings me down everyday. The girl thinks we’re still friends but I hate her so much. What do I do?? PLEASE HELP
