My younger sister needed money to leave a difficult situation. I had savings set aside for a large wedding. I transferred most of it to her and told my fiancé I had made a bad investment.
He was upset but eventually accepted that we would have a smaller wedding. Years later, I finally told him. He was silent for a while and then said, "You could have trusted me enough to tell me." That hurt because he was right. I thought I was protecting everyone, but sometimes secrecy is just another form of control.
