Not a good idea man, getting married and all. Especially when you're younger, but its rightfully your call
Depends on who is marrying whom, their relationship, their current position in life, and how they perceive themselves. My grandmother was married at 16 to my grandfather who was 17 or 18 at the time. They had never even met before. But they stayed together for 60+ years until death and had 4 children together. They lived close to family and Loved each other for who they were. They learned to fix the little things and big things alike, and live life together. Even through poverty and discrimination.
At the same time, some people feel that marriage closes many doors socially if you marry too young. Some people don't want to be just "comfortable", or be with the same person each day, or can't cope with little things that happen. Some people are afraid of the idea of marriage or children. In order to get married you have to make a commitment that
everyone is frightened by at some level. You have to be able to compromise, and Love, and appreciate, and laugh.
