He Told Me He Would Kill Himself if I left

I was 17. He was in his early twenties. “He’s cute.” My friend whispered to me one day. I agreed. We had both just started working a new job and were smitten over the new guy. I didn’t know much about him other than that he always wore a hooded sweatshirt and his mom sometimes brought him lunch to work which I thought was cute. We became fast friends.
