That's the harsh truth.

Men already make money, strength, dominance, they are already men, they don't want another woman that is trying her level best to imitate being a man.

Do women realize how weird that is? Imagine being in a relationship with a man that is trying his best to be a woman.

The only kind of people that "accept" non-feminine, masculine women that don't adhere to traditional gender roles do so only because they view women simply as a series of holes and need them only when they are horny - like sex dolls.

Men that want their woman to adhere to traditional gender roles and femininity are demanding a personality from a woman. These men do not want to view woman as a series of holes and would like them to have qualities other than their holes so that their woman would be important to them in occasions other than when they're horny because they view women as actual human beings and refuse to degrade them to a point where they are seen simply as sex dolls and comfort machines.

If your man is Okay with you not adhering to traditional gender roles and femininity it's because he views you as his personal sex doll and comfort machine.

Women, think about it this way: If your SO only brought money to the table would you secretly view him simply as a walking dildo with in-built meal ticket mechanism or much much more than what he deserves?

EDIT:

which will be better? A masculine man that knows how to be a man paired with a feminine woman that knows how to be a woman. or A semi-masculine man that knows a little bit of how to be masculine and a little bit of how to be feminine paired with a semi-feminine woman that knows a little bit about how to be feminine and a little bit of how to be masculine. Imagine a team comprised of two people. In scenario A, person A and person B knows a little bit of a whole lot of things whereas in scenario B, person A knows everything about half of the work and person B knows everything about the other half. Which team would produce better results, value each other more, need each other more(and therefore make compromises more so as to avoid conflicts more) etc?
