People don't think about that shit when they go to get married. Like here in the U.S. The divorce rate here is really high and it costs a lot of money even well after the marriage over, but people still get married anyway.
There was this one girl I used to work with I had a crush on. She ended up meeting some guy and getting engaged after 6 months. In less than a year, they were married. 6 months after that, they were divorced. Gee, I didn't see that one coming.
