I M Afraid of Relations

Didn't know where else too post this. But it's this guy I talk to off and on.. he's like 3 or 4 years older and I explained to him that I don't know what I want but I like him and like talking to him and all that good stuff .but that he needs someone is his league I was like you have everything I'm a kid compared to you . Be he insist on waiting for me he says things like you we may date others eventually but in the end it's me and you.. and I'm not going to give up idk what to do i don't mind being friends but I know he wants more
