Yeah, as pretty much everyone else said in some form or another-- the people who are looking for passion instead of reliability are also most likely the people who can't STAY in a relationship (let alone a marriage)....

Personally, I've ALWAYS wanted someone who would be my best friend, but then I also think the "Jolly Holiday" scene in Mary Poppins is the most romantic scene in all of moviedom, so I may be weird on that count.
