Dud, chicks don't have to make the sacrafice, it is just the approach everybody take. When it comes to relatioship it is about been able to adapt to one and other. For example, men usually prioritze their career and refuse to stay home to take care of children, while women on the other hand are more willing to do so.
Basically, it is the 21th century, so there is no longer such thing as men's role and women's role, but frequently people still fail into the old fashion pattern, once in a comitted relatioship, especially after marriage, it is just the way things goes, for some reason.
by the end of the day, relatioship is about two people and sometime, also involve those other people around them (their family and your family). It is about whether you two are compatiable and whether you are comptiable with their family. For example, if a man date a woman from a culture that believe a man should adopted a woman's last name after marriage, for a lot of guy, this is a deal breaker, but for man from that culture they would be Ok about it. In contrast, in the west, adopting the husband's last name is a big deal and if a woman refuse to do so, it might cause conflict, where in Asia on the other hand, we don't care about stuff like that, so the man's family won't care whether the wife take the last name or not.
So, by the end of the day, it all depends on the people you are associate with
