Regarding what somebody said here on this thread, it is not true that it's impossible to find a devout Catholic spouse. There are many here on this site who seek out spouses. My own children who were seeking devout Catholic spouses found them, not without a long search, but they are there. They only need to be brought together. I remember a particular SSPX priest saying that we need to help to bring these people together. I don't know what he had in mind but there is certainly a need there, though not insurmountable.
You bring up another good point -- devout Catholics exist, but they might not be a "10". You know, they won't make all your friends jealous. They don't look like magazine cover models.
But I guess we all pick our poison, and choose our priorities.
Personally, I'd make "solidity in the Faith" one's primary priority and deal-breaker.
Remember the old song, "If you wanna be happy for the rest of your life." That song contains the common folk wisdom of the ages. Beautiful women will likely not treat you right, and will always be sought after by other men even after you are married. But if you marry a somewhat less than glamorous woman, she will be grateful for the love and attention and will be faithful forever.
But it's not as simple as beautiful vs. ugly.
The problem is the "pop culture ideal of beauty" which is promoted through worldly movies and pornography. While it's true that beauty is objective (not in the eye of the beholder), it's also true that priorities and "taste" has changed over the decades, which proves that those things are NOT objective.
So the problem is not just that men want a beautiful wife, it's that they want a wife who The World in 2017 considers beautiful. The only reason for that can be PRIDE.I'm sure most women have a good feature or three, which you could focus on. Also, every man shouldn't have the same taste -- unless they all have the same upbringing (American movies, pornography, etc.)
Men who are lacking in virtue are, by definition, going to be more or less slaves of LUST and PRIDE. These vices will command and warn them to "not settle for less" or else "you'll never get to be with a gorgeous woman, and you won't be able to live with yourself." This is obviously the devil talking. These men are pushed to desire a "10" so they can appear in photos and in public like an action movie hero posing with their supermodel wife hanging off them. It's the classic "trophy wife" syndrome.
Last but not least, I want to address another delusion of the devil. Namely, that if a man marries less than a "10" he will be forever tormented (tempted to sins against the 6th and 9th) whenever he encounters a truly beautiful woman at work, public, the store, etc.
This is RIDICULOUS because a man has to get used to telling himself "no" more often than not, regardless of his vocation or who he is married to. Let's run the math:
Number of women a married man can lawfully be with: 1
Number of women in the world: 3.5 billion
I'd call that "more often than not" you have to check yourself, cut off your thoughts, tell yourself "no", etc.
The vocation of a priest, religious, or single person is simply adding a "NO" for that last "1" woman in addition. So he has to be perfectly chaste with 3.5 billion women, instead of being perfectly chaste with 3,499,999,999 women like married men do. See my point?
Chastity, continence, and purity are virtues required by ALL, not just the "poor saps who couldn't manage to get married".
Archbishop Lefebvre called marriage "a school of chastity" or something to that effect.
If you think otherwise, you're 3/4 of the way to mortal sin.
