My boyfriend showed my nudes to people..

Je

My (now ex) boyfriend got drunk and showed my nudes to his friends at the bar.. I took his phone and deleted every single picture of me that shows even a little cleavage(these go back 5 years). But, this isn’t the first time this happened and I’m SO embarrassed. He’s acting as if it doesn’t even matter and that I’m overreacting.. am I wrong to be this upset?
