Is it a good decision?

i personally feel that at the age of 18 youngsters have alot more to see in life and are not as mature to make their decisions for their entire life to come..moreover it's essential that couples become financially independent befor ethey marry..which is really not possible as per the requirements of marriage at 18.

No I don't think it is a good decision,coz by 18 no one(boy or girl) will have enough awareness about married life and i dont think such cases will last longer.

That's not really wise to allow it , however it's maybe nice because girls might get pregnant and guys might like to fix what they did so they can get married by this way But if you don't have any good reasons to get married then you shouldn't!, because you are going to make a family and you should be able to earn enough money to feed them and make them live in good way!
