Cheated by guy

Hi I was in relationship with a guy for 3 years. He used to text on social media that he loves me he loves me . He somehow tried to convince me emotionally and stuffs. He tried to get close to me in smart way. I was still 16 years. We met eachother when i was 16 years. He got close when i was 16 years and he was 19 years. Because of his family issues he used to not talk to me properly. Before that every day he used to text whenever i text he used to reply no matter what the time is with in 1 or 2 mins he used to reply even in mid night. I was addicted to him. And when he left me alone suddenly i started fighting. And i had no one to share my feelings so i shared it with my friend. My boyfriend didn't like that and he saw my friends texts and told me to stop texting my friend. And i even stopped but one day my friend texted me and my phone was with my boyfriend he saw that and asked me to unlock my phone but i didn't do. So he came to my home. And tried to kill me 3 to 4 times by closing my nose and mouth with pillow, and he made me swallow 3 dollo tablets, he bet me , messed the house, kicked me. After that he emotionally somehow convinced me. Later he emotionally spoke words like in your husband who else should see you expect me , and forced me for physical and i agreed. He made promises of marrying me so i agreed for physical relationship also. Whenever we fight i used to beg him not to leave me so in return he used to ask my nudes. And he blocked me everywhere giving reason like i texted my friends about him so he had blocked me. After that to make him stop Asking my nudes i created a fake snap chat account like someone treatning me by sending mine and his nudes. This i showed him and told my phone is hacked so i told not to share private pics on devices or not to capture private pics of us. He used to forcefully capture private pics of mine and him and videos also. I did that many times and lied him it's not my account. After that whenever he used to fight even if the mistake was not on my side i used to go beg him. He used to beat me. Kick me. Scold in foul languages. And all this came till parents. After everyone telling me not to talk to him and he refused to stay with me. I still went behind him. Thinking it's my mistake so he left me. Because he used always blame me and never gave reason like he himself doesn't love me . He always told it's me who made him worst and not love me. After break up i still stalked him and i created fake accounts and stalked him. And with my old account which even he knows i changed it to his name and texted his one friend with his name to know who she is. Now he has complained on me in police station. I don't know what to do. How to prove. He has all proofs against me. I'm confused. Please give me a proper answer on this
