A romantic relationship is a partnership. Like any partnership, the parties may be equal but they are not the same. Each has individual roles and responsibilities. Those roles and responsibilities may change per circumstance or even over time. Those roles and responsibilities should be determined by the parties involved, not outside influences (e.g. family, society, etc). The parties may choose to have "traditional" roles and responsibilities, but it should actually be a choice and based on what is best for the relationship rather than due to outside pressures.
In many parts of the world, the rights of women have increased. While I am an advocate for women's equality and would even suggest more improvement is needed in many social areas (not just geographical areas), the social equality of women has come with an unfortunate downside.
One downside is some women have transitioned to a competitive relationship with men. "What men can do women can do better." While that idea might be useful and motivating in the workplace (or not, depending on your perspective), it has no place in a romantic relationship. A successful romantic relationship cannot have any kind of male-female competition in it.
Unlike men who can often be competitive and still maintain a very close relationship (though not always), competition for women almost always results in negative feelings associated with the other person. These negative feelings will result in a breakdown, or break-up, of a relationship unless very decisive steps are taken to prevent it - which rarely happens because the negative impact of the competition is not even recognized until it is too late.
