Guy's Behavior

I Feel like he only does that to me?

So I stopped messing with this guy it’s been a few months now and he still will write me on social media. Like try to get my attention he still passes by my house and just still keep trying to get me to sleep with him but I keep telling him no. So yesterday I guess he got upset again and started calling me names and saying he was going to leak my nudes and stuff if I didn’t come see him and sleep with him. I still ignored him he then started sending me them. I told him to delete them he told me I had to come get his phone to delete them. This not his first time acting this way then later apologizing. I don’t get it though because we not together never was but he used to tell me it was just me he’s sleeping with but whole time was lying when he would get mad like this he would send me other msgs of other girls saying they coming and on their way. So that’s how I confirmed it so it’s like if he got all of these girls I don’t get why he act this way and won’t leave me alone. I don’t get why he can’t just continue to mess with them it’s like 4 of them. And I’m sure he doesn’t disrespect them like he does me if they were to say they not sleeping with him anymore.
I Feel like he only does that to me?
