I am a resident of Chicago. I have been marrried with my wife for almost 6 years now. We have one child. Last year during a confrontation, which has been going between the two of us for a long time,  my wife kept on saying that she is going to leave me, and in rage I said the following sentence:

 “I want to divorce you.”

we again had a huge fight between the two of us, during which I uttered the word ‘Tallaq’ twice.

Now my wife thinks that she has been divorced, although she is not sure about it either. What do the scholars of Islam say about the matter defined above.
