Yes, you may still be able to find a man. But either he is attracted to other qualities you can provide apart from yourself (e.g. the wealth of your family, or your own wealth), or he is with you because he is not good enough to get a younger woman.
"Younger" is the keyword. Youth, or the beauty of youth, has a magical power over men. And from the end of your 20s, you are discriminated upon because of your age. And this is a discrimination that is much more difficult to legislate away than just lower pay for equal work. Because this discrimination is in the minds of men who feel sexually attracted to younger women. They cannot be forced by the law to be attracted only to women of the same age.
Thus, for married women in their 30s, it is, in most societies, not a realistic alternative to break up a working marriage, just because she wants to experience again the delight of a newly developing romance, and we would not advise a wife to give up easily a working marriage.
Instead, while the working marriage will satisfy the first emotional need (the feeling of security in a stable relationship), the second emotional need (the delight of a newly developing romance) is best met by being unfaithful and having a lover. I am aware that this advice will not be understood by girls and young women who are not yet married. As long as the first emotional need (the desire to have a man forever) is not met, most girls and young women are not aware of the fact that her emotional needs may well split after some years. This is the case because obviously, at the beginning of a romantic relationship of a young woman with a man she wants to marry, both needs are fulfilled in the same person (the romantic need and the need of the security a lifelong union should provide).
For all the above reasons, and even though it will sound strange to some, and immoral to others, I proclaim that a woman needs more than just a husband to have a fulfilled life. She also needs a lover, and quite possibly more than once, especially if the woman is beautiful.
