As I said earlier, people prioritize differently when selecting a romantic partner. But ultimately, for a relationship to last and become fully-relaized, you need personal connection, sexual attraction, and mutual commitment. All three of these factors are equally important in a long-lasting relationship. If any one factor is lacking, the relationship as a whole is lesser for it, and becomes less likely to last.
I can provide a counter point to that, but it's one of those "exception to the rules" situations.
It was about an author, a famous one, who's name escapes me at the moment (I know, not helping). Long story short, he had a slew of mistresses, some of whom were actually good friends with his wife. After his wife died, he became a broken shell of a man, because, even though he'd had all these affairs, he'd lost his best friend.
Not sure what I'm adding to the discussion, here, but simply not all relationships can be judged on the same set of values. Think about those relationships that last, even though nobody thought it had a chance.
