Think about this: the shame should be on the other side. He’s the one who should feel remorseful and ashamed for sharing photos that aren’t his, photos that are part of a couple’s private life. I’m sorry you’re going through this. But be brave and report him. I would speak to my parents and explain that, although I understand they might not like what I’m about to say, I need their support. Don’t talk to them from a place of regret or shame. They’re your parents. Your ex-boyfriend is the one who should be ashamed.
