Getting married and making a family for a child means you will have to support yourselves. In most families both the father and mother work. It is possible to support yourself and the baby on your own, but it will probably not be easy. One or both of you may not have graduated from high school yet. While there are jobs around that don't require a high school diploma, these usually don't pay very well and have very little future.
Some careers take lots of schooling.
Marrying young may not close any doors for you, but it is likely to make them harder to open. If your family or his offers to let you live with them, think about how well this will work. These are all things you will want to talk about honestly before you get married and before you move in with your family or his. Someone who hurts you or makes you unhappy before marriage is likely to keep on doing so after marriage. If either of you has a problem with alcohol, drugs, gambling, promising to change if you get married is a promise you may not be able to keep.
