Was editing that, but mkay.
"That is, if they haven't reached an agreement after a month or two of debate, should the guy or girl conform to one side, or they reach a compromise. <---(took me five minutes to finally get the word, holy shit)."
Okay, so...well, you also mentioned the father, and supposedly, if one gamete belongs to the father, and the other the mother to make a zygote, that would give the father (or...it should, but that's debatable) partial ownership of the zygote->fetus->whatever the child might be.
But if law has already established the fact that a fetus is exclusive to the mother, then...well, by law, she gets to decide by herself. [A case of abortion could be contested for feticide if the father prosecutes / sues, though the chances for him to do so successfully are low. This will probably end up on a headlines if it gets high enough in the court system, which might spark another debate] <---A little far-fetched, but that what I could predict if the father is that desperate.
On the other hand, if the father does somehow force his partner to give birth and she does, and she manages to set up a lawsuit for duress and sue for damages to her virginity (or now, what's left of it and the value of the child in question, I might think that the case will probably go for more in the mother's favor with the pro-choice laws in place. [Again, it might be debatable and make headlines and controversy, but that's a stretch.]
On a side note, am I still an idiot?
