[Anna:] "I'm not defending him, it's nothing to me; but I imagine, if you had not cared for those pleasures yourself, you might have got out of them. But if it affords you satisfaction to gaze at Thérèse in the attire of Eve..."
Anna is jealous, and doing a bad job of hiding it, even though she knows her jealousy is unreasonable and unfounded. However, having been isolated from the rest of society, she fears losing Vronsky as well.

"Why mine?" said Anna. "After yours I don't want another portrait. Better have one of Annie" (so she called her baby girl). "Here she is," she added, looking out of the window at the handsome Italian nurse, who was carrying the child out into the garden, and immediately glancing unnoticed at Vronsky. The handsome nurse, from whom Vronsky was painting a head for his picture, was the one hidden grief in Anna's life. He painted with her as his model, admired her beauty and mediaevalism, and Anna dared not confess to herself that she was afraid of becoming jealous of this nurse, and was for that reason particularly gracious and condescending both to her and her little son. (5.9.12)
Anna's jealousy is cropping up more and more often. Here she's worried that Vronsky is interested in Annie's nurse.

His jealousy had in these few moments, especially at the flush that had overspread her cheeks while she was talking to Veslovsky, gone far indeed. Now as he heard her words, he construed them in his own fashion. Strange as it was to him afterwards to recall it, it seemed to him at the moment clear that in asking whether he was going shooting, all she cared to know was whether he would give that pleasure to Vassenka Veslovsky, with whom, as he fancied, she was in love […]
Levin is so easily jealous of his wife that his imagination runs rampant when Veslovsky indulges in some harmless conversation. Why is it that Levin believes that Kitty is in love with Veslovsky?
