What should I understand by that now?

I'm w13 and my friend asked me if I wanted to play with him and I keep it clear. Then he asked 5min later "is it okay if we gamble tomorrow I'm playing now" save the world (is in fortnite in the same game what we wanted to play together another server and he just wanted to play it alone) ". I have Now nothing said except "Okay no problem." Doesn't he want to play with me now or what's going on?

Yes it seems.

You can ask him.

Why don't you ask him that yourself? You can ask friends anything! And you should too!

Probably

In my eyes, that's not a good friend

Why are you asking us and not him?
