well first of all my opinon is dont do.
your asking us whether or not you should have a baby with your boyfriend. which shows me your not ready and dont really want a baby at this time.
you sound like you have a sensible head on your shoulders, you want to go to college and everything. how do you know he is gonna stick around once the baby is here.
do not let him pressure you into anything! and to be honest if you tell him you dont want a baby and he dooesnt stick around then that shows everything really.
if he really wants to be with you and loves you he will respect your decision.
remember a baby is a big responabilty! i know people say its for the next 18 year but really its from the moment you concieve till the day you die. a baby will not always be a baby but they will always be your child!
seriously sit down and think about what you want! listen to yourself and no one else. us girls are always here for you.
good luck
