He said “I got you on lock”

this guy & i have been talking since march it’s never been anything more than friends w benefits although we do other things that couples may do. i told him in the summer that i like him as more than that & want something. he simply told me he wasn’t looking for a relationship & that he is in his hoe phase and doesn’t wanna hurt me. whatever whatever. clearly that didn’t stop me so we still talk all day everyday and do our thing. the other night i was messing around and was like “ damn you so fineee” and all he was wearing was sweats and a hoodie. he was like “that’s how i know i got you on lock. you think i look good when i ain’t even looking good” does that mean he thinks no matter what im gonna be there just bc i do everything a girl friend does without the title? or what does that even mean in a guy perspective? just don’t want him to take me for granted or anything.
