Three Talaqs will take place and you will become Haram for each other. The husband will neither have the right to revoke the divorce nor to renew the Nikah. Without the process of Halala you will not be able to go back to your husband.
NB. Halala, a woman marries another man, consummates the marriage and then gets divorced again or he passes away, in order to marry the former husband.
وان كان الطلاق ثلاثا في الحرة وثنتين في الأمة لم تحل له من بعد حتى تنكح زوجاغيره نكاحاصحيحا ويدخل بهاثم يطلقهاأويموت عنها
(الفتاوى العالمكيرية ج.1 ص.473 كتاب الطلاق باب الرجعة)
