I had a dispute with my husband, and we agreed on divorce and on the support for our daughter. He left the house for four months, and one day he called me and said very calmly: Do you want a divorce? I answered: Yes, and he said to me: You are divorced, you are divorced, and this was the final divorce. After a short time, he told me that he asked the Fatwa House, and they informed him that the divorce does not take effect because it was an unofficial divorce, and I am convinced that it is a divorce. What is the ruling on the divorce?
