Via consensus, men are allowed to marry women 'of the book', being Jewish and Christian women. Not the other way around. So you would have to divorce her.
You should look at this Quranic verse, too:
Allah says: “Do not marry idolatresses (al mushrikāt) till they believe, and certainly a believing maid is better than an idolatress even though she would please you, and do not marry idolaters (al Mushrikīn) till they believe (hata yūminū), and certainly a believing slave is better than an idolater, even though he would please you. These invite to the Fire, and Allah invites to the Garden and to forgiveness by His grace, and makes clear His revelations to mankind so that they may remember.”Qur’an 2:221.
It is haram for all. You cannot marry atheists as a man or a woman.
