Something I regret

So the night of the 4th I got really drunk and I guess I was snapchatting some people. one thing led to another and I accidentally sent nudes to one of my guy friends (I'm in a relationship and I guess I thought I was sending this pics to my bf). Never have I ever had cheating tendencies and I don't even remember sending those pics. The only reason I know I did is because my bf woke me up angrily because he had gotten on my phone and read a message from one of the guys I sent the pics to asking if I remembered, which I didn't. I feel like complete shit because the last girl my bf was with cheated on him and I never wanted to hurt him. He acts like he's over it but I'm not, I feel like trash honestly. Half his family knows what I did, and a few of his friends. I'm not sure how to cope with this... help?
