am i being groomed ...?

look odd title ikkkk but theres this guy that talks to me tho he doesnt live anywhere near me (i mean countries away) and he hasnt necessarily said anything bad but hes way older hes in college and im in my first year of highschool and i feel like its weird that he still talks to someone my age but i also feel like if i block him or smth its like completely undeserved yk? he hasnt even been weird and lowk all we talk about is like games or general stuff
