Can you help with answer?

I may be young but I think he wants to know if you talk about him. Like when you are in a conversation do you ever say, "Yeah I was talking to Dave (or whatever) today and he said the funniest thing." and they'll ask who Dave is and all that. Maybe? Hope I helped.

If he said, "have you told your family about me yet?" then it means he thinks that there is something to tell. He clearly values your convos and thinks that you guys are a little closer than mere acquaintances.

Hey there. It's hard to say really. Does he perhaps think there's more to it than just acquaintances? Sounds like a nice friendship to say the least. Perhaps he's looking for a closer connection with you.
