What should i do about this?

Ok so you probably think i'm exaggerating about this...but i really need good advice.

so theres this boy and my moms friends with his mom and grandma.. his uncle is annoying the crap out of me saying oh this s his girlfriends..his uncle invites me everywhere but i dont wanna go bc i dont like his nephew hes so boring and he has no social life i feel bad but i told my parents that im not interested but i know there joking around but its so annoying and the boy tells hes uncle that we could be friends but the thing is that hes just so boring and all he talks about is video games but he doesnt even talk to me at all

ok im not trying to sound like a ***** but i just need advice bc hes family thinks that i should be hes girlfriend but no...thanks :)
