So kinda typical subject

So a while back this guy and I got talking as we both went to same school(I don't go to that school anymore) anyway he asked me to send him some nudes over snapchat and I did(DO NOT JUDGE!! I know it was stupid I don't need anyone to rub it in any further) anyhow I ended up telling my friend who was quite pissed about it and she said she told him he was a dickhead and all and then he blocked me on snapchat, now I hate leaving thinks badly so I messaged him tonight over Facebook and he replied and then is said have I done or said sir thug to upset you... He saw it but hasn't replied. What do I do? 😔
