I don't think a woman should ever need any sort of consent from the man to get an abortion; there should be absolutely no legal requirement for the man to have any role in that decision-making process. That said, if a woman is impregnated by a man with whom she is in a relationship of some sort, my personal opinion is that the decent thing for her to do is to talk it over with the man before getting the abortion (I've been in this situation and greatly appreciated that we talked it over instead of her getting one without mentioning it to me). But, legally, his desire in the matter should be irrelevant; if they talk it over and he's adamantly against the abortion and she still wants one, that shouldn't make any difference in her ability to get it done.
