I'm proud of you for being an adult being mature and bringing this up to your aunt. Having done shameful things myself in the past and bringing it up to my family I have an idea of what you went through so I know it took some strength props. I am not happy without your father reacted and hope that it is only an emotional reaction and in a day or two will calm the fuck down. Give your aunt a big old hug and a kiss on the cheek for us
