how do I cut off this dude

we started being buddies because we both like listening to metal until he just somewhat clinged onto me when I was taken, and when I was single he always gave me mixed feelings, he said things guys wouldn't say to their female friends or wtv but he was feeling romantical but when it comes to a point where I try to do the same he just like..denies. he keeps joking on how he's gay (he's srsly not) and its just kinda ticking me because I don't understand this dude. basically, he just loves bomb me with out us being in a relationship like..HELLO?? e

either way, idfk how to even block or cut him off without inflicting his feelings AND him noticing at all, he always likes my stories and status and we have a streak on tiktok
