Taylor.....ask for feedback and you shall receive. My very first thought after reading this question is that I would suggest to you that being so young now, you would do well to give yourself more time. More time not only to think deeply & analyze, but also to establish yourself in the job market, set up housekeeping in a comfortable environment and it is never too early to research good child care (since I'm assuming you'll be working full time)
Babies are everything sweet and wonderful.....and also expensive. This is one of the simple unavoidable facts.
To be honest with you Taylor, you might want to be more concerned with the practicality and permanence of a child, than you seem to be about choosing your dear friend as the father.
As you describe him, and the close relationship you have, I'd say the decision to procreate is a very personal and private decision between the 2 of you.
As for further advice......You might want to read peeples response over a few times. She has suggested some EXCELLENT questions you need to ask yourself....and seriously focus on the answers.
Best of luck to you...
