Marriage

recently got my nikah done but my father added a condition of monthly expense to my wife if there is any difference between us without my consent. As there were many guests I looked at his face to please consent with me but he didn’t consent with me and got ahead with that condition. please tell me what would islam say about it and further to add in the same evening that thoughts came to mind and in that thought just randomly thought came if wife demanded that i would divorce her. It was totally random and had no clear intention. it was all in my mind. Please guide me in this scenario and further ruskati has not been placed.this all happen in mind kind of waswa and didn’t spoken or written anything
