Would this count as harassment? (Lengthy!!)

Freshman in college here, I've been at school for just about two months. All was going very well at first, and then I befriended a guy down the hall from me. He seemed really cool at first, funny and trustworthy; I thought nothing was wrong. He started to like my friend and once he realized she had a bf he moved onto me. I had/have (it's complicated) a thing w another guy in our building and he tried to sabotage that my trying to set him up w other girls and telling me that they guy I had a thing w/ was trying to hu w/ other girls. He would also pretend to be more drunk than he actually was and try to cuddle with me, even when I tried to pull away. He kept shit talking the guy I liked to me after I told him to stop, and he kissed me on the cheek and tried to go for the lips after I pulled away. I told him that I strictly see us as friends and only friends, and he responded "well I see us dating". He also made a group chat w my 3 best friends I've made at college purely to talk shit about me, he tried to guilt me into liking him and giving him a chance. I told my parents what happened because it was causing me a lot of anxiety and my dad confronted him when we ran into him and his family at dinner. My friends told me that my dad overreacted and I shouldn't have said anything. They're still friends with the guy to this day and I still feel awful about it. I feel like they don't understand my side of things and since then I feel like I'm kind of an outsider looking in on the group of us girls and I don't feel as happy anymore. Some days are better than others but I can't stop thinking about it. I blocked this guy on all social media but I don't feel any better. Am I overreacting?
