As a man who has been married to two women in the U.S.
I can tell you that there is no "one size fits all" approach to marriage by women or men.
Everyone has (their preferences or must haves) they want in a mate. Some people may consider them to be shallow but nevertheless each person is entitled to want or desire whatever makes (them) happy.
Among these could be a certain level of attractiveness, healthy, money/income stability, height, weight, no drama from exes, loving, an idea of what he wants for them in the future and so on.
Note: The expectations of marriage also change for individuals as they age or evolve. One woman's "perfect mate" at age 18 may not be what she would have chosen at ages 25, 35, or beyond. Some women say "yes" to marriage simply because "it" not (him) has been a lifelong desire. He's just a prop!
Ultimately the goal is to find someone who shares your same values, wants the same things for the marriage, naturally agrees with you on how to obtain them, and last but not least there is a mutual depth of love and desire for one another.
