support/advice?

I'm 5 weeks along right now and it's mostly planning, to be honest it was an accident and I'm fairly young. My boo, the guy who got me pregnant, is happy-scared but happy except he keeps talking about how much he's going to work and he's already been gone (oil field-camp)for 4 of these 5 weeks. I don't know if I can raise a baby on my own and I don't want him to take on all the money things but I don't know what to tell him...
