There are a few reasons why they think this way. The first being that many of them grew up in fatherless homes where they had no model marriage to observe. If one doesn't have a stable marriage to observe in their lifetime, they would think that no stable marriages actually exist. To them, stable marriages are really just a facade to keep up appearances, but deep down both parties are unhappy. I'm sure we can both see the ridiculousness of that train of thought: you can't possibly know the intricacies of what someone else is going through unless you experience it for yourself.
The next reason is they have friends that keep telling them not to get married. All of their friends are in unsuccessful marriages and tell them about how unhappy they are, so they have these impressions about marriage that make them think all marriage is bad. The problem with this train of thought is that your friends tend to think just like you, and sometimes even have the same (poor) taste in women as you do. It's not surprising that most of these dudes would have failing marriages when the real motivator behind getting married to begin with was wanting to be with an attractive woman. It's fine to want to be with someone who looks hot, but that CAN'T be the
only criterion you use to determine a potential mate
Then of course there's the issue of most of these dudes wanting to marry a whore and hope that she'll eventually turn out to be a good housewife, but know this never works. Then they say that marriage is a scam and will lead to male financial destruction. Well of course it will. Whores have no moral compass (hence being whores), so they generally don't care about
you or pleasing you. That kind of thinking will lead to the destruction of any marriage.
All of these things are why you have to choose your partners CAREFULLY. Stop using your dikks and use your damn heads! There's a reason why I ignore many of the women who approach me or show interest in me. They show no redeeming qualities whatsoever and show little to no wife potential. Some are hot, some are ugly, but almost none of them strike me as the type to hold you down.
Actually, I think the easiest way for someone to find a good wholesome woman is to be a virtuous man yourself. If you ask a woman to do so much, you too should bring just as much to the table.
A man of virtue can easily attract women of virtue, and these are women that aren't trying to destroy your marriage and take your money. They are women who will hold you down and truly love you. They'll be the left to your right and the sun to your moon.
