Of course, but you also don't want to tell young women they have all the time in the world to settle down. If they want multiple children, and by the time they're 25 they still haven't found a man they expect to marry, they really need to get on that.
I guess we're thinking of children along separate lines - I see it as a potential outcome of a good, stable relationship, but you're defining it as a goal, where the getting a mate is a step in the progress towards said goal. It's just a different way of defining relationships and lives.
I think having kids is a goal for a lot of people, e.g. the girl that is the subject of this thread.
>She has a career, and wants to get married and start a family sometime soon. Her boyfriend is a great person to be around and she adores him, but... he doesn't want kids (and is actually freaked out by them).
