Most rape victims are raped by someone that they know, so it's a good chance that if a woman is raped that it's her spouse that did it.
Can't help those that choose to be in that situation. They shouldn't marry people they think will rape them. I sure know it was one of my criteria. If they feel they raped them while in marriage, they can choose to divorce them, and than they can get their abortion. the law covers this scenario and allows abortion after divorce.
