Why the need to grow up so fast?

I'm officially 21-years old as of two weeks ago.

I have to use more than the two hands God gave me, to count the number of people I know my age that are expecting a baby, have a baby ((or three)), are engaged, and/or married.

More numbers.

50%.

The divorce rate.

Half of all couple who marry - divorce.

I would bet you that an even smaller percentage of the still-married 50% are sticking together for love. There's always "for the kids," "for the money," "because I'll end up in the hospital if I try to leave..."

Then, on the complete opposite side of the love universe, you have these ridiculous romantic movies that preach "true love" and "soulmates."

How are we, as humans, supposed to compute this information? Is there some sort of balance between the perfect cookie cutter movie and the disturbing truth of statistics?

I myself come from divorced parents. Both have been through a number of relationships. Growing up with that makes it hard to wrap my head around couples that have been together 50+ years.
