The man's opinion has nothing to do with the decision to abort the child. If the father eventually runs off, guess who will be stuck with the child, alone? The woman, of course.
9 months in a woman's life is a long time. Do you see the insanity of a man telling a woman that she must do something with her body for 9 months because he wants her to? If the man cares so much about having a child, he should marry a anti-choice woman.
Other than that, it's her choice. And, the United Supreme Court has consistently found this to be the case.
