And people in worse situations still manage to do a great job, what's your point?
What he's feeling now is fear and shock over sudden life changing news. His life isn't over, and he will come to realise that. I'm not giving a single anecdotal point of view. Sure, I'm talking from my own experience but it's also very true that a large number of pregnancies are unplanned. Thank fuck all parents in that situation don't follow your advice.
And he has absolutely no right, nor should he, to deny any sort of financial responsibility. He got a girl pregnant, why should he get to walk away from that while she doesn't? Remember, abortions aren't always an option if if they're the desired outcome.
