False harassment

One day, i made a call to a friend of mine to whom i want to discuss an exam related query. I was trying to talk to her for a week before that. I had discussed the query to her boyfriend over phone who also suggested me to talk about it to her but i had no proof of it. So, when i made the phone call, she reacted angrily and told me that she blames me for harassment and she would tell "others". I tried to justify but she didn't listen and blocked me. I tried to tell her the truth on email but got no answer. I was scared, so I tried asking her boyfriend to tell her the truth. He kept lying to me about it. He told me that he would discuss the matter which obviously was not a big deal. But then, later, he started threatening me that her father is senior govt. employee who would sue me. I thought of contacting her brother. But before doing anything, i told them that what they are doing is wrong and i texted them to tell this matter to her brother. I don't know what happened after that but i got a call from a person who claimed to be her brother and even he, without hearing my side if story, blamed me for stalking and following her. He told me that i think i am a friend then i should act like one. I did that. I stopped contacting her in any way. About 10 months later when the newspaper started picking up the same issue which i tried to tell at that point of time, i tried to prove her my side of truth. I emailed her and wrote everything in that email. All the events and the dots connecting them. I got no response. I didn't even know if she had read it. So i am under severe depression because of everything happened. I made myself very clear to them that i only wanted to help. I never had any intention of interfering in anyone's life. I was just a friend and only wanted to leave like one. I called her boyfriend. He told me that they have taken that email in consideration and everything would be fine. Afterwards, i got no response from them. So, i told her boyfriend that i am trying to contact her brother and asked him to help me to prove my innocence to her brother. I never stalked her and never followed her. I don't even know her address. I looked for a way to contact her brother. I found few people with her brother's name but only one matches the working details which i was told by herself when we were friends. From her brother's website, i got a phone number. I called on that phone. Someone picked up. I didn't know who he was. But he said that Rahul (her brother) lives outside and asked me about the matter. I started telling him but then the connection went down. When i dialled again, the same girl picked up and started abusing. I told her that i am trying to talk to her brother not her. Then, i got the call from her boyfriend and her "brother" who started threatening me to file a false police complaints against me. This happened 3 months ago. I am scared that in future if anything happens, they would straightaway blame me & which could affect my life
