I hate that one, too. We were married when I was 19 and my husband was 18. He graduated high school two days before our wedding. Both of us started college, but did not finish. I knew I wanted to be a stay at home mom, not a career woman, so what was the point, kwim. He had a job from age 14, so all that work/school exhaustion had already set in. Sooo many people assumed I MUST be pregnant or we wouldn't be getting married. I think there were some who even thought when our first son was born (over a year after our wedding) that I was.
There are people who think we threw our lives away by getting married young. (both of us had full scholarships that we did not use) I have no regrets. Sure, there are things I might do somewhat differently if given the chance, but overall, I love my life. I had some female complications a few years after my last son was born. If we had not married and had children early, I might never had had the chance. While I don't think that marrying young is always the right thing for every couple, I would definitely not discourage a couple who truly loves one another. We have been married almost 18 years. My husband made the comment a few days ago that not only are we growing old together, we grew up together. I think that is a sweet thought.
