What is the ruling on someone who cursed "religion" while angry, and did not intend the religion of Islam; does divorce occur between him and his fiancée because of that?

Reviling the religion is an act of disbelief (kufr), and the perpetrator is not excused by anger unless that anger leads to a loss of awareness. The فقهاء (jurists) have stipulated that whoever reviles the religion has apostatized, because it is more severe than treating it lightly. The one who reviles must offer sincere repentance. Reviling the religion affects the marriage contract (nikah). If one of the spouses apostatizes, the marriage contract is annulled according to the majority of jurists. They differed, however, on the necessity of renewing the contract if the person returns to Islam. A specific individual cannot be declared a disbeliever until the conditions for declaring disbelief are met and the impediments are absent. It is advisable to consult with scholars for a detailed explanation of the matter.
