oomis hate to break it to you, but “kashe shidduchim kekrias yam suf” wasn’t recently made up. My grandmother recently told me that shidduchim were hard than too. Maybe not a “crisis” but shidduchim were never easy.
As far as divorce is, i also know many divorced people unfortunately and the most i would say, is that only in one case the girl was too naive to pick up a serious problem.
Marriage is not friendship. it’s a whole different realm, you are forming a LIFE together, towards one goal, building a family, raising children al pi torah… that does not have that status of friendship. And didn’t they tell you, one of the first things when you got engaged that your choson is NOT your “new best friend”? it’s much more elevated.
