16 Year Old Getting Blackmailed. What Do I Do

I won’t give too much information for my safety but i’ll still try and explain as much as i can, please bear with me if this is a little vague. When i was 15 years old, i was stupid on the internet. I was homeschooled and completely cut off from the outside world and so desperately wanted to meet people. so i went online to do so. I joined this app that was made for making friends, not dating. on there a man messaged me. he was 41. i talked to him a bit and told him that i was in fact 15, not 18 which he was okay with. I talked to him for about a week and then untimely blocked him as i realized what i was doing was wrong. he made fake numbers, fake accounts. calling me nonstop 24/7. now here is where i’m obviously in the wrong. he offered me money if i continued talking to him which i accepted. i thought that as long as it’s just chatting online..no problem right? wrong. about five months goes by and i try and stop talking to him again. but this time was different. he had too much information on me. he said he NEEDED to see me or else he would report my parents to ICE. (my parents are legal citizens) and report them to cps. i love my parents dearly,but theyre strict. i over shared a bit about how strict they were and he says if i do not meet him and date him forever (or just have s*x with him) he will do terrible things. is there any way to escape this situation without my parents finding out? he knows where i live and threatens me with that information he has also threatened to harmed me if i do not stay with him. i can’t do anything about me being a minor since we both live in oklahoma and due to terrible oklahoma laws it’s okay to them. this was very rushed but today he is making terrible threats and i simply don’t know what to do.
