I’m currently a freshman in the middle of my second semester. I had gotten close with this guy in one of my classes and thought that there might’ve been ~something~ there. After a couple chat/study sessions, I realized there probably wasn’t going to be a romantic connection but hoped to maintain a friendship. On one of the study sessions, he had locked the door behind him. This made me uncomfortable and I began to leave. He asked if I was interested, and I replied with a friendly and awkward, “I think we should stay friends.” Naturally, things died down a bit in out texts, but he began being incredibly persistent and defensive over me “ignoring him”. He will invite himself into my residence hall, sit himself next to me if I’m studying someplace public, ask my roommate about my whereabouts, and I believe I’ve seen him on my very specific running routes. I’ve gone to my RA, and it was suggested I write him an email. What do you say to such a sensitive and persistent person?
