About the fact that a woman is created as an assistant, it is said in the 2nd chapter of Genesis. The main purpose of a woman is to be an assistant to a man: (Genesis 2: 18,20 "And the Lord God said: It is not good for a man to be alone, I will make him an assistant, corresponding to him ..." And the man called names for all cattle and birds of the sky and all the beasts of the field; but for a man there was no assistant like him "). A man can not be full without a woman. Just like she without him. (Genesis 2:24 "Therefore a man shall leave his father and his mother and cleave to his wife, and they shall be one flesh"). Being an assistant does not mean being lower or worse than a man.
The confusion comes from the word "helpmeet", we assume it means assistant but it means so much more. The bone was taken from his side, not his foot. I believe this is symbolic for partner. The general characteristics of a man and a woman are complimentary. Another point to consider is that the further the creation process went the more "advanced" the creations were; man was the final act of creation but woman was the last creation and the crowning glory of God's creations.
