My advice is don't do it. 18-year olds don't have the maturity to deal with the pitfalls of marriage, let alone life. At 18, the couple is caught up in the puppy love stage. "I love you baby, smoochy smoochy muah muah." Love alone won't cut it, meaning it takes more than love to have a successful marriage. This couple must be able to weather the storms that married life brings: Richer or poorer, sickness & health, better or worse. Take time to experience life, get established in your education & career, then revisit marriage.
