One bit of wisdom I like to impart on young men is the fact that finding the one is highly improbable. There are billions of people out there. There is no guarantee that a perfect match happens by a certain age. Some relationships are only meant to last ofr a certain time. Not that you should not attempt monogamy, just that you should not lose yourself in the false promises, myths or fantasy embedded that is romanticized about it.
A relationship takes two and a whole lot more.
Contrary to popular belief you can always be friends with a woman without having sex, or having to marry her. It is completely legal. It is also very healthy and critical to our interdependence.
