I think a lot of people are unrealistic. They don't understand that marriages require work and maintenance. I mean, you can't just plant flowers and never water them and expect bitch want for sex them to flourish. But people don't that they need to actively maintain their marriages. I also think a lot of people get married to early, particularly those who are against premarital sex. I think those people end up marrying someone who they are not sexually compatible with because they do not know what they are looking for in a sexual partner. And, the opposite happens as well people find someone they are so sexually compatible with they fail to notice that they are not emotionally compatible with. And I just don't think 20 years olds have experienced enough to recognize when they fall into either of those categories. And getting married due to pregnancy is a very poor predictor of marital longevity.
