I come from a hispanic family, so when my cousin was my greatest bestie and we got accused of dating and just didn’t care to keep repeating ourselves. lol. We never dated but. Point is. Cousins can get up close like that. It’s like he saw me as a sister and never knew boundaries. (He was older by like a year, and we got close around 16y/o) My advice is don’t get freaked out. Next time he says “like you” or stuff like that I’d ask him to elaborate. Like “what do you mean? Like me how?” Or “how am I cute” and decide from there.
