I happen to favor young marriages. I think the shopping around in the twenties makes for harder hearts and silly expectations. If someone has slept around, I believe they are more likely to continue to do so when married. Behaviors get set in cement as we get older. As for the changes that take place, they'll still rear up in the thirties, forties, and fifties.
thats what I think.
I think people mess up with they start thinking in terms of "I" instead of "US".
Hmmm, I think losing trust is worse for a marriage than selfishness.
