correct me if im wrong but i think he/she can still convert to his/her original religion .. take the case of Ruffa Gutierrez (Ms. World Second Princess), she was married to Yilmas bektas who was a muslim and follows islam since then, unfortunately since marriage didnt work out, she came back to the Philippines, been baptized (again)...

yes, there is  a divorce... good luck to you!!

Life's like that but still can't give it up
