Well I was 22 when I got married, and my hubby was 24. We have only been married for a little over 2 years, but we have had an incredible marriage. We also had been dating for about 5 years before we got married, and we felt ready and mature enough to get married. I totally think it is just a matter of how mature and ready you are for the commitment. I even have a friend who got married at 18, and they just celebrated their 5 year anniversary and are as happy as can be. Guess it depends on the person and what kind of goals and life they want for themselves.
