He's 14 and he wanted to get married? Why would he? I think these kids don't understand the whole package that mariage represents. If they did, they'd embrace the stag life. Drive motorcycles, travel to exotic places, take up an adventurous line of work, be a complete lunatic. Can't do these things when you're married kid.
Its not about just getting the girl. You got her, good, now what. I'll tell you what. You got responsibilities, pay the bills, get a house, get the groceries, pay for the car, take her shopping for things you can't afford and definitely don't need. Surprise, she's pregnant! And what does that mean for you? More responsibilities! Pay for her health care, get baby stuff, obsess over names, get into fights, almost get divorced over your preferred names. Kid's born now, pay for medicines, food, new stuff that's redundant every two weeks. Time for school, cough up more...
Its just going to keep going on. I'm not trying to portray marriage as some dismal dead end, I think you need to be at least past your midlife crisis before you can do that but if some kid out there thinks that marriage is easy and you can manage a married life as a 7th class ka bacha, you need to give yourself a whack on the head and realize what you're fully, the commitment you're getting into.
