Omg. She was being cruel to you, then she couldnt believe it when you turned it back on her, when you said, "you didnt raise THEM." She knows exactly what you meant, she just thought you couldnt figure it out? Or what? Honestly, my brother once said something similar to me, and then he was like, oh how can YOU be so mean? I was like, ME? Did you hear what YOU just said? Really, its not even worth arguing with them. They are arguing with their own past selves, their own personal disappointments.
