Divorcing one's wife before meeting her in seclusion

I did niakah with my couisn in 2015 but we never met alone and we never spoke. My father and mother fought because of my father in law. I told them to stop and at that time I loss my mind and I said abusive words to my parents that "you people are dogs, I am giving her divorce divorce divorce, now keep quite. I already gave her 3 divoce so no more fighting otherwise I will do sucide". Then my parents were normal. I said those words unintentionally and I didn't know about the rules of divorce.
