Think about this:
what if it's not even YOUR baby? lol You make her go through with the pregnancy and find out it's another dude's kid.
Also, when do you start paying child support? Not while the baby is still in the mom. Therefore, the man's "responsibility" is after child birth, not before. Legally, the woman is entirely responsible.Therefore, it is her decision to have the baby or not.
If the man convinces the female to have an abortion, after she can legally have one, who will be charged for murder? The one legally responsible: the female.
Of course she should consult with the father - it's called respect. But ultimately, it's her choice.
