Crush tip

I’ve been crushing on this guy since freshman year! I’m now a junior and he a senior. At one point we sent “pictures “ but both stop since his dad a cop and we just thought it was wrong . Anyways at one point I told him I like him and even ask for his number which he rejected me. Now a year later we hit each other up again and been making jokes and sending selfies. Well now he says things like he can’t sleep he horny or I want you and you want me too. I do still like him but I don’t want to be used for sex you know ? I repeatedly would say things like sorry find someone else or nah. It makes me confused cause sometime he seems concerned for me but other times we won’t talk for weeks . He doesn’t like my insta pictures but is the first to see my insta story and Snapchat story. He likes things on twitter wanting a girlfriend but last year said he Too busy. I really like this guy and I want him to be interested but i don’t want to put myself out there to be hurt.
