Made someone feel like shit and i feel bad

Went on a date yesterday , we were texting non stop since we met (online , a week ago) and everything kinda was going fine , but the date was real weird and awkward and dude gave me the ick many times and at the end he said "love ya" like NO . I also noticed that he's actually autistic and honestly i cannot have any type of connection with him , he's not even my type . We were doing fine before the date until i got back home and i just can't feel the same about him , i can't fake shit and i don't feel like talking to him anymore . Like bro is so weirddd and a (lil creepy?) . So I've been ignoring him since last night like barely texting him and ik how it looks like after coming back from a date and i really feel bad cuz he's been ghosted , used and ignored before . Idk what to do now i don't wanna make him feel bad and either way , telling the truth is going to hurt him . Idk what to do or how to behave now but i just know i don't want him in my life .
