the time comes for marriages to end

It's crazy that my friends and people my age are getting married. I'm super happy for them, of course.
I just wonder how some people are so sure of someone else at this age (or at any age, for that matter) that they could get married. Mind you, I would love to get married one day. I want a family of my own. I simply have yet to find the person who I could stand to be with for that long and be that sure of.
That being said, I've always liked love a great deal.
