How to tell someone your not interested

I feel really bad because ive been talking to this guy and we've met up and we are supposed to be going out again next week. We have each others snapchats, instagrams etc and hes invited me to his bands gig later in the month. However we have only been speaking 4 or 5 days and he wants to text cobstantly and always asks to facetime. Tbh its kind of gave me the ick because i like my own time and space and ive decided that im not ready for a relationship and now idk what to do because i feel like i've led him on and he thinks there is more of something there than i do and i feel like a **** person and idk what to do.

honestly just tell him straight up don't drag it on any longer he'll be hurt either way so just get it over with and make sure you leave no room for interpretation that might leave him to think there's still a chance, and its okay you don't need to feel bad you don't owe him anything you figured out you didn't see it going anywhere and so you're allowed to back out!!

Do what I did: tell them how much you loathe and hate them

Controlling friend: "It is haram!"
OP: "Is it? that's a shame as it tastes delicious! (orders giant cup of gravy)
OP: "Yum!".

You tell them that you're not interested

What?
