So I'm 18, and virgin, and I didn't have sex but I sexted my ex and we sent nudes.. normally, he sent his penis pictures only, and I sent my boobs and belly along with my face..

now we have broken up since 2 months because he was cheating on me.. and when I said him rude words, he said he had my pics and sometimes texted me ":)" this symbol. I don't know what he smile about and it freaks me.

I'm in a relationship now with a new guy who doesn't know about all these shits.

What do I do if my ex leaks the pictures? does he have it or just threatening me??? I'm totally screwed, and I can't eat of drink or sleep without that horrible thoughts now. please help.

###EDIT : I sent him nudes a year ago, and we have no contact on social media from then. he just texts me on phone sometimes with that weird smile. I'm horribly sorry for sending nudes, I got carried away so badly.
