Relationships

Hey guys sorry I'm asking this anonymously but I'm pretty sure the two people I will be talking about are on here and I'm trying to be a little cautious.. Lol. Anyways I was dating this guy that I fell in love with, he went to my school, we did everything together and he was my first with literally everything. After 8 months I missed the feeling of being independent and since he was going to college I felt like we both needed to explore our options. ESPECIALLY BECAUSE HES AT COLLEGE!!! So we broke up, although he didnt want too. He made lies about me to his parents so they could hate me and tried many times to get back with me. Two days after the break up he messaged my bestfriend at the time. Asking if she would want to go to the movies with him, she agreed, but only as "friends". They started dating shortly after that. Tell me if im wrong but he is only dating her to get back at me, or to still know how I am because theres no way he got over me that fast. Her and I are no longer friends although I miss her, but I want him back. Am I wrong for wanting him back? And if I do want him back or if I should try how?
