The trifecta of everything that went wrong
I was a senior in high school. I had previously briefly dated a guy my junior year. I thought he cared like I did (he took me to his senior prom) and his family really liked me. Turns out that he was just a player and he decided to stop talking to me and hung out with another girl at a show we were at. Completely ignored me and I was devastated.
Flash forward to senior year and I had just been broken up with by someone I really cared about, who I thought I loved. this guy cheated on me with a younger girl at his house which was 3 down from mine. Again, devastated. So I started hanging out with guy number 1 again. Nothing serious but I was too uptight around him to trust that he was being sincere. I knew his reputation and it had only gotten worse the longer I knew him.
