What is the relationship between friendship and judgment in the story?

In Wharton’s short story Roman Fever, he discusses the friendship between the characters Mrs. Ansley and Mrs. Slade. Although their status remained as friends even though Mrs. Slade knew about Mrs. Ansley’s secret admiration towards her husband, she continued to be friends with her. However, the relationship between Mrs. Ansley and Mrs. Slade was never truly sincere ever again. Usually, friendships between two individuals influence their judgment, however, Mrs. Ansley and Mrs. Slade differ in how their judgment influenced their friendship. Mrs. Slade was unaware of the secrets Mrs. Ansley had which concealed their true intentions. This leads to keeping the friendship although Mrs. Slade knew about her feelings. In the end, their judgment also led to the end of their friendship. Mrs. Slade asked why Mrs. Ansley was sad for her and at the end of battling it out, Mrs. Ansley reveals that she had Barbara. Wharton intentionally ends the short at that line because it shows how their relationship was truly insincere and full of lies. Friendship should be made of people who truly care for each other and respect where it is a judgment-free zone. However, that one line represented that the friendship and judgment they both had were corrupted with jealousy, lies, and insincerity.
