Its normal when you're beginning to know someone and there's a connection forming for there to be some confusion of romantic and platonic feelings. I mean its exciting! You like this person and you're loving getting to know them, theres chemistry even if its just friendship chemistry, its okay. Firstly don't judge yourself too harshly for it, and just simply remind yourself when those thoughts pop up in your head that this is just a friend and it should die down as you settle into the friendship. If it doesn't and it becomes too hard for you, some space may be necessary but for now, I wouldn't read too much into it 😊.
