Is it too late?

I think I might have made a mistake lol
So this guy wanted to date me for about a month and a few days ago we finally had the conversation where I told him it’d be better if we stayed friends.
The only problem is now I think I want to be more but I doubt he’ll be interested anymore
Should I tell him or keep it to myself?

Nice update: I told him, and he wasn't mad as I expected- he actually wants to plan a date so woo!
Is it too late?
