How can I get my guy friend to see me as more than friends?

for reference i have this close group of friends, my bsf gracie, and two guys we will call ben and colin. i basically grew up with ben, he and i were close family friends and went to the same middle school. we went to hoco together, and at one point we liked eachother, but then we both agreed it was better to stay friends to not risk our friendship. he shows a lot of interest also, and gracie and colin have told me ben likes me

anyway, this isn't about ben. i like his friend colin. colin is better friends with gracie, but she knows i like him and is super supportive. he's super attractive, he has really kind eyes and super cute freckles. he's the sweetest guy, but he's also super fun to talk to and hangout with. he's the least boring person i know, and he has the most contagious smile i've ever seen.

it seems like colin shows a little bit of interest, but i don't know if im mistaking it with friendliness because our whole group is really close. at homecoming he asked me if i wanted to leave the party and go walk around alone, and we spent the whole night tg. another time when we were all hanging out we were kinda teasing him cause his phone wallpaper was like the default one, so we said he should make it a pic of me and gracie. then he took a pic of us and told gracie to get out of the picture and he made his wallpaper a picture of just me. anytime we go out he asks me how he looks, if he smells bad, to fix his hair or button his shirt etc. he's also said that if he had to kiss a girl at my school, he would kiss me.

besides all of that, this is kinda embarrassing but one time gracie dared me to kiss him so i tried and he rejected me and said were js really close friends and "we can't", but he's also super touchy like holding my hand and fixing my hair or wiping my face?

i reallyyyy want him to see me as more than a friend but i was thinking maybe it's because ben likes me? how do i get him to see me as more than a friend?
