I was dating Matt for a total of 8 months. The first 2 months we lived in the same city (last summer), then I moved across the States for university and we were long distance.
So me and Matt never talked about being exclusive, or even about whether or not we should call it a relationship at all. We were young, the sex was amazing, and for 18 year old me this was all I cared for, so even though it was clear that he is not husband material, I liked him because he was the "bad boy" type, dealing weed at school and all that jazz.
So when I moved he told me he loved me and we started to get a little more serious but still obvious that this was a temporary relationship very much based on physical contact. I was visiting him once every month and a half ( i am much better off financially than him so it wasn't an issue that he couldn't visit me), we saw each other for like a week and had a lot of sex. In the times between, naturally, we texted every day, and sexted quite often, and we would exchange nudes prett much weekly. Now he sent nudes much more rarely than I did, and for a long time I refused to send any but I did send one and loved his reaction. Loved it so much that I started sending more and more, more creative poses, showed him everything from every angle basically. Helped my confidence greatly! The good thing is that I always cut my face off but it is still obviously me ( i have a tattoo on my back). His nudes were basically just close up shots of his package and it could be anyone.
Fast forward to a few months ago, he suddenly stopped talking to me, WHILE I was visiting him. I did send him a lot of messages asking for an explanation and blew up his phone with calls because I was really upset. He told me to leave him alone, that I was getting too serious with him and too clingy, for wanting him to hang out with him after spending hundreds of dollars to see him apparently. At the same time, his ex before me that has been also studying abroad was also back in town at the same time, so while I don't have concrete evidence that they did anything, I know 2+2 equals 4. Anyway, I respected his wishes, was sad for a week but with ice cream, wine and good friends I got over it and moved on.
About a month ago he started messaging me again. I didn't answer so he kept spamming me, saying he's really sorry, that he misses me. I'm not interested in him at all anymore, I am currently with someone else and we are an actual couple, not some parody of a relationship like me and my ex were. I talked to my ex briefly and told him what he told me before - to leave me alone. Except that he kept messaging, saying he'll send my nudes to everybody including my mother if I dare not answer. I went on my mom's facebook and blocked him on it just in case but I don't know what to do. Do I have copyright on these photos? I doubt the police will care. Some pictures are quite embarassing.
tl;dr: ex boyfriend's feelings for me suddenly rekindle after him telling me to leave him alone, now he threatens me with sending my nudes around if I don't text him back and I don't know how to go about this blackmail. Any advice, reddit?
