All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
Divorce does not take place if the one who writes it did not intend to initiate divorce, as the majority of the scholars are of the view that writing the word divorce is one of the metaphors for divorce. So if what had happened at the first and second time when the wife claimed you divorced her was just writing the word divorce, then they are not considered as divorces. The majority of the scholars are of the view that if the wife claims divorce while the husband denies it, then it is the statement of the husband that is taken into account, as it is him who can initiate a divorce, so divorce has not taken place. This is their ruling even when the wife claims that her husband has divorced her by uttering the word divorce but the husband denied it. So how can this be considered a divorce when your wife only claimed that you wrote the word divorce and signed divorce papers, while she knew that you were not determined to divorce her by writing the word divorce. Therefore, she is still your wife.
As regards your saying to your wife 'I want divorce', then we did not understand what you meant by it, anyway, this expression is not considered by itself a divorce. Divorce takes place only according to the scholars who are of the view that any expression by which the husband intends divorce.
Finally, we think it is more appropriate to take the matter to a Shaysh in your country or to an Islamic centre.
Allaah Knows best.
