Here is an awkward ques cocos!🫢

Do boys hit on their older cous sisters? Like my cousin whos younger by js 1 yr have been actin a lot diff lately. we're distant cousins and we don't see eachother much like once a year maybe. He's been texting me nd stuff and calling me by my first name and i kinda smell something by his behavior. 💁🏻‍♀️ So chat am i over thinking stuff or is there something (Ps- once we were in a call and his friends threatened him by saying "njan parayate, parayate" and he hung up the call in a sec.) Isn't that pretty weird?

Edit: i didn't knew whom to talk to about this that's why im asking this here
