Yandere sanscest oneshots

So help?

alright so I know you read the title , but I need some help before I update you all. I recently got into a relationship- and it was going well for about a week or two . But afterward a person in my first period saw me and my boyfriend . He asked if I was dating him and I said yes , he gave me a scared look and told me of his story . He said his ex girlfriend broke up with him because he was too clingy and possessive. Afterwards he stalked her on all social media sites and at her own home . I was shocked , and he also told me that I could ask any of his friends and even certain teachers about the matter. Later he told me that he was in love with me , the guy who told me the story of his ex. So then I thought , oh he probably wanted to scare me into wanting to break up with my boyfriend and to get with him. But later on I noticed some of his tendencies were a bit possessive, I would find him staring at me while I eat , and he followed me wherever I went . I asked his best friend about it , and told him the story I was told. He said that he could neither confirm nor deny that it was true . I was scared , and shocked . I need some help on what to do. Should I find more intel on this , I am so scared and confused . I think I may be dealing with a real life yandere , and he doesn't like when I get close to other guys . Or even my friends. And now he wants my Wattpad account and other social media's .
