[color=navy] If I was your guy friend, I wouldn't act out any proposal of responsibility just yet. After all isn't the girl involved with another guy? How can your friend be sure that the baby the girl is carrying is the other guy's? Before that, how sure is your friend that the girl is pregnant? Just because she said so?
If your friend is my friend, I would advise him to wait and see if the child the girl is carrying is truly his. Since your friend is a successful engineer in a US-based company, he could well afford a paternity test. It might be a bit expensive but nothing compared to taking care of a child that does not genetically belong to him.
