The Woman's Responsibility in a Relationship

For the past few days, I have been reading blogs written by Single Black Male aka "SBM". I enjoy the way he articulates his opinions and thoughts. As of recently, those thoughts revolved around the interesting courtship between women and men. In his most recent blog, " Moving on...", He states "One thing I have not heard at all is what is the woman’s role in things. What is she responsible for? What does she need to do to make the relationship work and prosper?"
Well I would like to answer that question.(Lets all keep in mind, my blogs are written based on my opinions and how I see things... If you agree..great..if you don't..great) To start off, as a young lady, I have always been taught how a man should and shouldn't treat me. At the same time I was also informed on how to do my part in order to maintain a functional relationship. Which is, the ability to put equal effort into the relationship. If I have something on my mind I should be able to verbally express it, but I must also be able to sit down and listen to what he has to say. Just like I expect him to compromise on certain situations, I must be able to do the same. Basically, I must be able to do all I expect of him to do for me or the equivalent. I am there to not only be his "Woman", but also his friend and vice versa.
I think many relationships disintegrate because someone feels unappreciated, and there efforts were not being matched. Which can correlate with a communication problem. If one is unable to communicate how unsatisfied they are, how do they expect their partner to know. For example, if he doesn't say "thank you" after a back rub, I may assume he doesn't appreciated them but expects them. When in actuality, he feels that because he constantly requests them, that I will assume he likes and appreciates it. Obviously a small issue made out of nothing, all I would have had to do is ask if he liked my back rubs, then everything would be fine.
All in all, a woman's role is either equal or equivalent to a man's. If its not, then it is a one sided relationship. And in one sides relationships, someone is bound to get fed up a leave.
