Cousin taking pictures of me while was sleeping

My cousin met this guy at the bar… I slept at her house and when I woke up the next morning she was taking a picture of us while I was sleeping the next morning… to send to this guy obviously they were texting. When I woke up she was trying to hide the phone so I wouldn’t notice…. But I saw her. How creepy..she needs to send him pictures of me. And try to hide it at that. She’s acts so jealous of me, just weird in general and posts bad pictures of me anytime she can.

I only saw one picture I dont know how many she was taking tbh…

What would you do?
