Guys help me

Hey so I like this 16 year old guy who's in college and I'm in year 10 and I'm 15 and I like him and I think he likes me... Well he says he likes me but I'm unsure so this is why I'm asking you guys for help. I like him and I want a cute relationship but nothing TOO serious as I'm still quite young but all he wants is pictures and Videos of me undressing to turn him on so he can wank and cum then he wants to be cute with me? if I don't send him pics he will say that I don't like him and threaten to stop talking to me... I really like him and I'm unsure what to do? 😁 should I just stop talking to him or should I continue but do what? I don't want to send pics?! Please help asap!!
