Um I NEED HELP:(

Umm... I didn't really get your question, but tell me if I'm wrong.

So your sister alisema something to wewe about your best friend. She keeps doing it and it annoys you. Now you've ended your friendship with your best friend because of that, and wewe want to know if wewe did the right thing?

So if that's the case, have wewe tried asking your sister why she lied about him? And I don't think wewe should end a friendship because of some lame gossip. And if you're doubting about the lies, have wewe asked his side of the story? With that he'll also know why you've ended the friendship (if he didn't know it yet).
