^That depends on what your asking. Do I think that you could couple up everyone over the age of 25 and they'd be happy together and willing to spend the rest of their lives together, no. Do I believe that everyone will at least love one person, yes. I guess somewhere in the middle then. Most marriages either work out (just barely) or end in divorce. A number of people fail to get married and a much smaller number do get married and stay in a relationship for a long time just because it's comfortable. A near infinitesimal amount of people actually finding sustaining companionship and love in their relationship. Do I think these statistics could be better, yes. Still, there are only so many good partners out there. A number of people are really horrid and no one would be likely to marry them, not even themselves. Not sure if that answers your question.
<That response was WAAAAAAAY too long.
vSame question.
