In America only the woman gets to choose to carry a pregnacy to term. No one can "force" a woman to have a baby or have an abortion. Most likely the woman is doing what she thinks is in her (best interest) with regard to her relationship with her husband or significant other.
A pregnant woman need only think about what SHE wants. It's her body. It's her decision. To put the blame on someone else for what (you choose) to do with your own body is a cop out. The only options a man has is to end the relationship with the woman or stay and abide by her decision. Legally we don't have say whether a child is born or not.
Ultimately when two people don't want the same things regarding a major decision such as children then they are wrong for each other. It's a bad idea to try an force a man into fatherhood. It's not doing a child any favors to have a dad who refuses to have anything to do with them. A woman should be choosy when it comes to having children with a man. Again it's a woman's choice.
