Equal?

Men and Women are equally dependent on each other and need the other in order to survive. Without one there can be no other.

Browsing the Internet, I came across this quote. When reading it I immediately thought about Krogstad and Kristine. During the story, Kristine discusses how Krogstad needs her and she needs Krogstad. I could not rap my mind around the reasons why. Kristine was working and earning money for herself and Krogstad was getting along just fine. It then hit me. Maybe Kristine does not want to work. Maybe she wants to live under a household ruled by a man where he does all the work and she gets to stay at home and watch the kids. Krogstad also probably wanted a wife that would stay at home and watch the kids. So in the end if they did get together both of their needs would be met. Kristine would no longer have to work and Krogstad would have a wife at home to take care of the household. If neither of them had each other, they would both be out of luck and have to do everything on their own. So maybe it is true that Men and Women are equally dependent on each other. What do you think?
