I dont know what to do anymore

I'm currently a high school senior at 16 and just got told by my 10 year old cousin that he thinks I raped him when I was 12. I dont know what to do. I'm scared, confused because he is lying but because he is a child I feel that if anything is taken to court I will have to suffer. The event he thinks occurred is not what happened. When I was 12 I had to stay at my cousins house during winter break since my parents weren't home during the day. I would stay in my uncle's room playing MW3 and my cousin would join me from time to time to play MW3 or beyblade. One day we had an argument and started wrestling and his pants came off because I accidentally pulled down on them. I jokingly said oh look we're alone and you're naked and got behind him but I helped him pull up his pants rather than do anything. I didnt know the that what I was saying or implying was something I couldnt say or do and I only said it as joke since i had just recently learnt about sex and didnt think it was that big of a deal.Nothing happened and we went on with our day and our lives. Nothing changed between us and he has never brought this up before. He still comes over to play on my ps4 since he doesnt have one and I have minecraft, and every time he says he wants to sleep in the same bed as me. Then on friday he causally said that i had raped him in my uncle's room that day. I was shocked at what he said and denied it but he said it a couple of times, and then he brought it up the next day as well. However he went on with his normal behavior and even said that he wants to come back next week. He is still young and I feel that if he tells someone what he is saying they will choose to press charges and I will be framed for something I didnt do. I always wanted to go to university to become a doctor and help people but now that seems impossible due to what he is saying. Idk if this is due to his home life, his dad stays at home all day and neglects him and he feels that the only escape he has is to go to his cousins houses, like mine and our other cousins. I havent been able to sleep properly, I feel so remorseful for saying what I said as a kid, with him assuming I was serious. Eating has become difficult and I all I can think about is what will happen if he tells someone. My whole life is in jeopardy for something i said accidentally as a kid, and I dont know what to do. I dont know whether I should tell my parents or keep this inside of me. I dont want to go to court or anything. I dont want to go to jail. I'm so scared and helpless and I feel like committing suicide at this point. And if this does get taken to court I wont have any other option then to do so. Nothing will be worth living for because everything will be taken away from me because of what i said when i was a kid. via /r/SupportForTheAccused https://ift.tt/3dqyuXW
