I married at 16. Had all 3 children by 21. I was sooo in love! I dropped out of high school, against my parents wishes of course. He was 9 years my senior, 25 at the time. He was tall, blond, handsome, and had a Harley. I had met him in May and by December we were married. Our first daughter was born when I was 18, our son when I was 19, and our youngest when I was 21. The early years were the hardest. 3 young kids and an income that had us struggling from paycheck to paycheck. He had nasty habits that drove me up a wall! If you can learn to ignore those habits, forgive the little things, never hold a grudge, it CAN and does work out.
Here we are 34 years later, 3 beautiful grandchildren and I'm still young enough to enjoy doing all the things kids love to do. Roller coasters, water parks, I can even throw a spiral football! I don't suggest dropping your education. That was our strictest rule. We insisted on a minimum of graduating high school and if you weren't going to college, you had a FT job. All 3 earned degrees, the youngest is working on her Doctorate in Clinical Psychology. The other 2 have Bachelors degrees.
Like I said, the early years are the hardest. But if the 2 of you can overlook the little things that irritate you about the other, forgive the little things and never hold a grudge, it can work! Good luck in whatever you decide. :-)
