You warped trad men with your obsessions!
Do you really think you should be talking to girls that age? They're too young to know what's best for them.
Why, they need to go to the university. And receive an education. And prepare for a career. And they will serve as beacons of Christian modesty and decency there. They will enliven the various social functions with their demure innocence. They will learn to drink responsibly in a "real world" setting. They will doubtless meet many nice young men, who may not be Catholic, but whom they can work on converting! Undoubtedly, that will be their highest priority when meeting a prospective mate at college!
And you warped, obsessed fellows need to wait for them to undergo this great experience, that will give them so much more insight into who is a loser, and who isn't. They will be so thankful to their parents for providing such an opportunity to them, and protecting them from those creepy trad men.
When they're finished, done with their wide-ranging experiences, then you will know for sure they're choosing you for you! Generally as a last resort!
If they still have the Faith intact, it's because they will have undergone a salutary trial. And if they've had a child on the way, they've given you the opportunity to be like St. Joseph.
These are Marian girls - lights in the profane, secular world, that they must enter into as preparation for Catholic motherhood.
