Good for you. But if she is three weeks then you need to sit down and really think are you ready for this. There are still options. If you haven't experienced all life has to offer, finishing college, getting a steady career, think about it seriously. You can still do all these things with a kid but once the kid is born your life takes a backseat. Your money, your time, your emotions will go into raising someone who needs you. Think on it. The shyt is just not a phase people go through. Kiss your sleep goodbye and watch how your fam changes on you. It's a serious life change. And these coli nikkas ain't gonna be there when you gotta change diapers, work two jobs, and have to deal with your baby momma's mom.
This is a YOU decision. Kids are great but if you are not ready the shyt is shocking. I had a homeboy who was too young to have kids and this nikka tried sellin dope to feed his daughter. Got caught by the police three weeks ago, now he is locked up and his daughter is calling another man dad (cause his baby momma wasn't shyt) Baby momma's are the scourge of the earth. Really think about this shyt.
