Been through that in social media and RL. The fact is, a real friend is not going to believe random gossip and lies about you. They will come to you and discuss, get your side and get the facts before making a decision.. When such fickle people are lost is really no loss at all. Consider it a favour done that these people are out of your life for they were never there for you to begin with.
You said that, beautifully!
Many 🙏
