Genesis 16:4 (KJV)
4 And he went in unto Hagar, and she conceived: and when she saw that she had conceived, her mistress was despised in her eyes. 5 And Sarai said unto Abram, My wrong be upon thee: I have given my maid into thy bosom; and when she saw that she had conceived, I was despised in her eyes: the LORD judge between me and thee. 6 But Abram said unto Sarai, Behold, thy maid is in thy hand; do to her as it pleaseth thee. And when Sarai dealt hardly with her, she fled from her face.
Why did Sarai blame Abram & appeal to the Lord to judge between them with this issue seeing she was the one who had instigated this, not Abram's solicitations?
