are my parents overreacting???

I started dating this guy formally a month ago. But hav had an informal thing for like 1.5month before this. 
My boyfriend and I were hanging out, and messing around NOT have sex, but haveing a little fun. Mom came home and cuaght us his pants were up, bug my shirt was off. My parents want me to quit my job. Brake up with him. Never talk to him. Deleted all social media from phone. I'm 16 turn 17 January 4th he is 17.
