I got married in June 2013 to a divorcee revert sister with 3 kids. Long story short we agreed a mahar of 500 pounds. We agreed that I could pay it later on. In July 2013 without any reason she asked for a divorce. The reason she said was that she was still in love with her ex husband. I did not want to divorce her but I only gave importance to her needs or wants. It was better for me to divorce her than for her to commit a sin behind my back. So I asked her over the phone what does she want. She replied " I will say release me and you say I release you ". So all I said was " I release you". Now is that a khul or a divorce ?
