IF YOU DONT WANNA READ THE WHOLE THING READ THE CAPS LOCKS AT THE BOTTOM

So i met this guy on grindr like a few days ago, and he was really nice, ladidida, you know how it goes.
Basically, we skyped a bit and then during the convo i realised how like, clingy he was. He was saying how he wanted to fly me to san francisco with him on a business trip, he wanted me to move in, skype him every day and take me out to dinner all the time... I was like wow man, i barely know you, this is weird.
Next day, i tell him it was really nice to speak to him but id rather not stay in touch and just move on, made some excuse how he was a great guy but i just didnt feel it or something. Like an idiot, i'd told him where i lived the day before coz he was gonna take me out (dont lecture me on how dangerous that shit is, i know already.) And he got really mad and said that he would screenshot the convos we'd had (most of which were not exactly PG) as well as some pictures id sent him and he would send them in the mail to my parents with no name so they'd open it and see it. (i live with them)
I was taken back and said, wow man, you're taking this way out of proportion, it's fine if we're friends i just dont think there's anything between us, im fine with seeing you couple times a month if you like but you know...
So now, im having lunch with him on thursday, and im actually a little bit freaked out. I've talked to him heaps, i know he's not mean and won't hurt me, but like, he's talking about the same things as before, like moving in and stuff, and i just want to forget about him...

BASICALLY, DOES ANYONE KNOW HOW TO GET RID OF A GUY WHO IS THREATENING TO EXPOSE YOU TO YOUR PARENTS (AND HE WILL DO IT), WITHOUT CAUSING SHIT TO HIT THE FAN
