<human>: A little background info: 
My boyfriend and I are both 19, have been together for a few years. In the last year we have moved out of home and into the city for university. 
Mid last year I met his uncle. Since the day I met him he was very sexually suggestive towards myself and I was told he was the same towards my SO's brother's girlfriend. He has even asked my SO if he would consider selling my nude pictures to him. Obviously the answer was no. 

I had my nipples pierced, and my boyfriend wanted a picture. 
So he took one on his phone, just a silly shoulders to naval photo. 
We soon forgot about it. 

Months and months go past since the snapping of the photo and we're invited to dinner with his grandparents, the uncle was invited also. 
Long story short the uncle goes "can I ring [my wife] my phone died" 
My SO gave him his phone, thought nothing of it. 

In the morning back at home he gets a text from his uncle. Opens up the message, and the previous message is sent from his phone to his uncle the night before.. the picture of my breasts sent to the uncle by the uncle. Obviously without our consent. 
We are completely outraged, I am very very unset and feel very violated. 
I don't know what to do. 
I spoke to him, expressing how wrong it was, how violated I felt and said he felt nothing was done wrong by me and wont apologise. 

not keeping nudes on your phone is the lesson I've learnt, but what do I do about the uncle now?

Can you condense the text into a few key points?
<bot>: SO's uncle sent himself a picture of my boobs to himself from from my SO's phone. I told him how violated I felt. He see's nothing wrong with it and wont even apologize.. Help?
